The problem is that on return from the externalEntityRefHandler() call-back
the parser currently assumes that parsing of the parameter entity is finished,
and updates its internal state accordingly. I do not have the time at this
point to implement and test a solution. Being able to suspend while parsing
the DTD is also less desirable than doing the same while parsing content.
to a parameter passed by reference (pointer). It seems that the processing
of return values is not standardized, even when calling convention and
platform are specified. This should make Expat more usable as a shared library.
declarations; these are needed only on an obscure platform (Windows NT
on PowerPC using GCC), and were never in previous releases of Expat.
They caused way too many spurious warnings on several platforms where
they aren't actually needed but should be ignored silently.
Removing these cannot break working code.
the use of modified default calling conventions in client code.
To deal with this issue and generally clean up the mass of macros
being used to support bits of the machinery, two new macros are being
added:
- XMLCALL, which expands to whatever is needed to nail down the
calling convention for all calls across the library boundary. This
must match the convention used for the system's malloc()
implementation.
- XMLIMPORT, defined to be whatever magic is needed to mark an entry
point as imported from a dynamically loaded module (.dll, .so, .sl,
whatever).
These macros are used to define the XMLPARSEAPI macro already being
used to define the API entry points. In addition, XMLCALL is used to
define the types of callback functions, and all example code uses this
explicitly in both the distributed applications and the documentation.
Implemented with two API additions:
1) For element declaration handler support:
XML_FreeContentModel
2) Exposing Expat's memory allocation functions:
XML_MemMalloc
XML_MemRealloc
XML_MemFree
* Changed macro for static linking from _STATIC to XML_STATIC
and modified expat.h accordingly
* Added ReadMe file to Win32 subdirectory documenting Windows builds
* Changed static build settings to create libraries with names different
from the Dll stub library libexpat(w).lib
behavior that all strings returned from Expat are affected by the XML_UNICODE
and XML_UNICODE_WCHAR_T feature-test macros, and ensure that an application
that needs to determine what type of character data is returned can do so
with reasonable ease.
API, allowing the implementation to define the structure and use less
casting in internal macros.
Change XML_UseForeignDTD() to return an enum XML_Error value, to allow
specific conditions to be reported more clearly.
which don't like spaces between the '#' and the preprocessor command.
* expat.h, xmlparse.c, xmlrole.c, xmltok.c:
- remove all spaces between the '#' and the cpp command.
