\section{\class{wxFileName}}\label{wxfilename}

wxFileName encapsulates a file name. This class serves two purposes: first, it
provides the functions to split the file names into components and to recombine
these components in the full file name which can then be passed to the OS file
functions (and \helpref{wxWindows functions}{filefunctions} wrapping them).
Second, it includes the functions for working with the files itself. Note that
to change the file data you should use \helpref{wxFile}{wxfile} class instead,
wxFileName provides functions for working with the file attributes.

\wxheading{Derived from}

No base class

\wxheading{Data structures}

Many wxFileName methods accept the path format argument which is by\rtfsp
{\tt wxPATH\_NATIVE} by default meaning to use the path format native for the
current platform.

The path format affects the operation of wxFileName functions in several ways:
first and foremost, it defines the path separator character to use, but it also
affects other things such as whether the path has the drive part or not.

\begin{verbatim}
enum wxPathFormat
{
    wxPATH_NATIVE = 0,      // the path format for the current platform
    wxPATH_UNIX,
    wxPATH_MAC,
    wxPATH_DOS,
    wxPATH_VMS,

    wxPATH_BEOS = wxPATH_UNIX,
    wxPATH_WIN = wxPATH_DOS,
    wxPATH_OS2 = wxPATH_DOS
}
\end{verbatim}

The kind of normalization to do with the file name: these values can be
or'd together to perform several operations at once in\rtfsp
\helpref{Normalize}{wxfilenamenormalize}.

\begin{verbatim}
enum wxPathNormalize
{
    wxPATH_NORM_ENV_VARS = 0x0001,  // replace env vars with their values
    wxPATH_NORM_DOTS     = 0x0002,  // squeeze all .. and . and prepend cwd
    wxPATH_NORM_TILDE    = 0x0004,  // Unix only: replace ~ and ~user
    wxPATH_NORM_CASE     = 0x0008,  // if case insensitive => tolower
    wxPATH_NORM_ABSOLUTE = 0x0010,  // make the path absolute
    wxPATH_NORM_LONG =     0x0020,  // make the path the long form
    wxPATH_NORM_ALL      = 0x003f
}
\end{verbatim}

\membersection{File name format}

wxFileName currently supports the file names in the Unix, DOS/Windows, Mac OS
and VMS formats. Although these formats are quite different, wxFileName tries
to treat them all in the sam generic way. It supposes that all file names
consist of the following parts: the volume (also known as drive under Windows
or device under VMS), the path which is a sequence of directory names separated
by the \helpref{path separators}{wxfilenamegetpathseparators} and the full
filename itself which, in turn, is composed from the base file name and the
extension. All of the individual components of the file name may be empty and,
for example, the volume name is always empty under Unix, but if they are all
empty simultaneously, the filename object is considered to be in an invalid
state and \helpref{IsOk}{wxfilenameisok} returns {\tt FALSE} for it.

File names can be case-sensitive or not, the function\rtfsp
\helpref{IsCaseSensitive}{wxfilenameiscasesensitive} allows to determine this.

The rules for determining if the file name is absolute or relative also depends
on the file name format and the only portable way to answer to this question is
to use \helpref{IsAbsolute}{wxfilenameisabsolute} method. To ensure that the
filename is absolute you may use \helpref{Normalize}{wxfilenamenormalize}. There
is also an inverse function \helpref{MakeRelativeTo}{wxfilenamemakerelativeto} 
which undoes what \helpref{Normalize(wxPATH\_NORM\_DOTS}{wxfilenamenormalize} 
does.

Other functions returning information about the file format provided by this
class are \helpref{GetVolumeSeparator}{wxfilenamegetvolumeseparator},\rtfsp
\helpref{IsPathSeparator}{wxfilenameispathseparator}.

\helpref{IsRelative}{wxfilenameisrelative}

\membersection{File name construction}

TODO.

\membersection{File tests}

Before doing the other tests you should use \helpref{IsOk}{wxfilenameisok} to
verify that the filename is well defined. If it is, 
\helpref{FileExists}{wxfilenamefileexists} can be used to test if a file with
such name exists and \helpref{DirExists}{wxfilenamedirexists} - if a directory
with this name exists.

File names should be compared using \helpref{SameAs}{wxfilenamesameas} method
or \helpref{$==$}{wxfilenameoperatorequal}.

\membersection{File name components}

These functions allow to examine and modify the directories of the path:

\helpref{AppendDir}{wxfilenameappenddir}\\
\helpref{InsertDir}{wxfilenameinsertdir}\\
\helpref{GetDirCount}{wxfilenamegetdircount}
\helpref{PrependDir}{wxfilenameprependdir}\\
\helpref{RemoveDir}{wxfilenameremovedir}

To change the components of the file name individually you can use the
following functions:

\helpref{GetExt}{wxfilenamegetext}\\
\helpref{GetName}{wxfilenamegetname}\\
\helpref{GetVolume}{wxfilenamegetvolume}\\
\helpref{HasExt}{wxfilenamehasext}\\
\helpref{HasName}{wxfilenamehasname}\\
\helpref{HasVolume}{wxfilenamehasvolume}\\
\helpref{SetExt}{wxfilenamesetext}\\
\helpref{SetName}{wxfilenamesetname}\\
\helpref{SetVolume}{wxfilenamesetvolume}\\

\membersection{Operations}

These methods allow to work with the file creation, access and modification
times. Note that not all filesystems under all platforms implement these times
in the same way. For example, the access time under Windows has a resolution of
one day (so it is really the access date and not time). The access time may be
updated when the file is executed or not depending on the platform.

\helpref{GetModificationTime}{wxfilenamegetmodificationtime}\\
\helpref{GetTimes}{wxfilenamegettimes}\\
\helpref{SetTimes}{wxfilenamesettimes}\\
\helpref{Touch}{wxfilenametouch}

Other file system operations functions are:

\helpref{Mkdir}{wxfilenamemkdir}\\
\helpref{Rmdir}{wxfilenamermdir}

is contructed (the name will be empty), otherwise a file name and
extension are extracted from it

\func{}{wxFileName}{\param{const wxString\& }{path}, \param{const wxString\& }{name}, \param{wxPathFormat }{format = wxPATH\_NATIVE}}

Constructor from a directory name and a file name.

\func{}{wxFileName}{\param{const wxString\& }{path}, \param{const wxString\& }{name}, \param{const wxString\& }{ext}, \param{wxPathFormat }{format = wxPATH\_NATIVE}}

Constructor from a directory name, base file name and extension

\func{void}{Assign}{\param{const wxString\& }{fullpath}, \param{wxPathFormat }{format = wxPATH\_NATIVE}}

\func{void}{Assign}{\param{const wxString\& }{volume}, \param{const wxString\& }{path}, \param{const wxString\& }{name}, \param{const wxString\& }{ext}, \param{wxPathFormat }{format = wxPATH\_NATIVE}}

\func{void}{Assign}{\param{const wxString\& }{path}, \param{const wxString\& }{name}, \param{wxPathFormat }{format = wxPATH\_NATIVE}}

\func{void}{Assign}{\param{const wxString\& }{path}, \param{const wxString\& }{name}, \param{const wxString\& }{ext}, \param{wxPathFormat }{format = wxPATH\_NATIVE}}


\membersection{wxFileName::AssignCwd}\label{wxfilenameassigncwd}

\func{void}{AssignCwd}{\param{const wxString\& }{volume = ""}}

Makes this object refer to the current working directory on the specified
volume (or current volume if {\it volume} is empty).

\wxheading{See also}

\helpref{GetCwd}{wxfilenamegetcwd}

\membersection{wxFileName::AssignDir}\label{wxfilenameassigndir}

\func{void}{AssignDir}{\param{const wxString\& }{dir}, \param{wxPathFormat }{format = wxPATH\_NATIVE}}

Set this file name object to the given directory name. The name and extension
will be empty.

\membersection{wxFileName::AssignHomeDir}\label{wxfilenameassignhomedir}

\func{void}{AssignHomeDir}{\void}

Set this file name object to the home directory.

\membersection{wxFileName::AssignTempFileName}\label{wxfilenameassigntempfilename}

\func{void}{AssignTempFileName}{\param{const wxString\& }{prefix}, \param{wxFile *}{fileTemp = {\tt NULL}}}

The function calls \helpref{CreateTempFileName}{wxfilenamecreatetempfilename} to
create a temporary file and sets this object to the name of the file. If a
temporary file couldn't be created, the object is put into the\rtfsp
\helpref{invalid}{wxfilenameisok} state.

\membersection{wxFileName::Clear}\label{wxfilenameclear}

\func{void}{Clear}{\void}

Reset all components to default, uninitialized state.

\membersection{wxFileName::CreateTempFileName}\label{wxfilenamecreatetempfilename}

\func{static wxString}{CreateTempFileName}{\param{const wxString\& }{prefix}, \param{wxFile *}{fileTemp = {\tt NULL}}}

Returns a temporary file name starting with the given {\it prefix}. If
the {\it prefix} is an absolute path, the temporary file is created in this
directory, otherwise it is created in the default system directory for the
temporary files or in the current directory.

If the function succeeds, the temporary file is actually created. If\rtfsp
{\it fileTemp} is not {\tt NULL}, this file will be opened using the name of
the temporary file. When possible, this is done in an atomic way ensuring that
no race condition occurs between the temporary file name generation and opening
it which could often lead to security compromise on the multiuser systems.
If {\it fileTemp} is {\tt NULL}, the file is only created, but not opened.

Under Unix, the temporary file will have read and write permissions for the
owner only to minimize the security problems.

\wxheading{Parameters}

\docparam{prefix}{Prefix to use for the temporary file name construction}

\docparam{fileTemp}{The file to open or {\tt NULL} to just get the name}

\wxheading{Return value}

The full temporary file name or an empty string on error.

\func{wxFileName}{DirName}{\param{const wxString\& }{dir}}

\membersection{wxFileName::FileExists}\label{wxfilenamefileexists}

\func{bool}{FileExists}{\void}

\func{bool}{FileExists}{\param{const wxString\& }{file}}

Does the file with this name exists?

\membersection{wxFileName::FileName}\label{wxfilenamefilename}

\constfunc{wxString}{GetPath}{\param{int }{flags = $0$}, \param{wxPathFormat }{format = wxPATH\_NATIVE}}

Return the path part of the filename (without the name nor extension). The
possible flags values are:

\twocolwidtha{5cm}

are two of them and the native one, i.e. the backslash is returned by this
method.

\wxheading{See also}

\helpref{GetPathSeparators}{wxfilenamegetpathseparators}

\membersection{wxFileName::GetPathSeparators}\label{wxfilenamegetpathseparators}

\func{wxString}{GetPathSeparators}{\param{wxPathFormat }{format = wxPATH\_NATIVE}}

\constfunc{bool}{GetTimes}{\param{wxDateTime* }{dtAccess}, \param{wxDateTime* }{dtMod}, \param{wxDateTime* }{dtCreate}}

Return the last access, last modification and creation times. The last access
time is updated whenever the file is read or written (or executed in the case
of Windows), last modification time is only changed when the file is written
to. Finally, the creation time is indeed the time when the file was created
under Windows and the inode change time under Unix (as it is impossible to
retrieve the real file creation time there anyhow) which can also be changed
by many operations after the file creation.

Aany of the pointers may be {\tt NULL} if the corresponding time is not
needed.

\wxheading{Return value}

{\tt TRUE} on success, {\tt FALSE} if we failed to retrieve the times.

\membersection{wxFileName::GetVolume}\label{wxfilenamegetvolume}

\constfunc{wxString}{GetVolume}{\void}

Returns the string containing the volume for this file name, mepty if it
doesn't have one or if the file system doesn't support volumes at all (for
example, Unix).

\membersection{wxFileName::GetVolumeSeparator}\label{wxfilenamegetvolumeseparator}

\func{bool}{IsCaseSensitive}{\param{wxPathFormat }{format = wxPATH\_NATIVE}}

Tests
are the file names of this type cases sensitive?


\membersection{wxFileName::IsOk}\label{wxfilenameisok}

\constfunc{bool}{IsOk}{\void}

Returns {\tt TRUE} if the filename is valid, {\tt FALSE} if it is not
initialized yet. The assignment functions and
\helpref{Clear}{wxfilenameclear} may reset the object to the uninitialized,
invalid state (the former only do it on failure).

\membersection{wxFileName::IsPathSeparator}\label{wxfilenameispathseparator}

\func{bool}{IsPathSeparator}{\param{wxChar }{ch}, \param{wxPathFormat }{format = wxPATH\_NATIVE}}

Returns {\tt TRUE} if the char is a path separator for this format.

\membersection{wxFileName::IsRelative}\label{wxfilenameisrelative}

\func{bool}{IsRelative}{\param{wxPathFormat }{format = wxPATH\_NATIVE}}

Returns {\tt TRUE} if this filename is not absolute.

\membersection{wxFileName::IsDir}\label{wxfilenameisdir}

\constfunc{bool}{IsDir}{\void}

Returns {\tt TRUE} if this object represents a directory, {\tt FALSE} otherwise
(i.e. if it is a file). Note that this method doesn't test whether the
directory or file really exists, you should use 
\helpref{DirExists}{wxfilenamedirexists} or 
\helpref{FileExists}{wxfilenamefileexists} for this.

\membersection{wxFileName::MakeRelativeTo}\label{wxfilenamemakerelativeto}

\func{bool}{MakeRelativeTo}{\param{const wxString\& }{pathBase = ""}, \param{wxPathFormat }{format = wxPATH\_NATIVE}}

This function tries to put this file name in a form relative to {\it pathBase}.
In other words, it returns the file name which should be used to access this
file if the current directory were {\it pathBase}.

\docparam{pathBase}{the directory to use as root, current directory is used by
default}

\docparam{format}{the file name format, native by default}

\wxheading{Return value}

{\tt TRUE} if the file name has been changed, {\tt FALSE} if we failed to do
anything with it (currently this only happens if the file name is on a volume
different from the volume specified by {\it pathBase}).

\wxheading{See also}

\helpref{Normalize}{wxfilenamenormalize}

\membersection{wxFileName::Mkdir}\label{wxfilenamemkdir}

\func{bool}{Mkdir}{\param{int }{perm = 0777}, \param{int }{flags = $0$}}

\docparam{dir}{the directory to create}

\docparam{parm}{the permissions for the newly created directory}

\docparam{flags}{if the flags contain {\tt wxPATH\_MKDIR\_FULL} flag,
try to create each directory in the path and also don't return an error
if the target directory already exists.}

\wxheading{Return value}

Returns {\tt TRUE} if the directory was successfully created, {\tt FALSE}
otherwise.

\membersection{wxFileName::Normalize}\label{wxfilenamenormalize}

\func{bool}{Normalize}{\param{int }{flags = wxPATH\_NORM\_ALL}, \param{const wxString\& }{cwd = wxEmptyString}, \param{wxPathFormat }{format = wxPATH\_NATIVE}}

operations on the path
normalize the path: with the default flags value, the path will be
