\membersection{wxMutex::wxMutex}\label{wxmutexconstr}

\func{}{wxMutex}{\void}

Default constructor.

\membersection{wxMutex::\destruct{wxMutex}}

\func{}{\destruct{wxMutex}}{\void}

Destroys the wxMutex object.

\membersection{wxMutex::IsLocked}\label{wxmutexislocked}

\constfunc{bool}{IsLocked}{\void}

Returns TRUE if the mutex is locked, FALSE otherwise.

\membersection{wxMutex::Lock}\label{wxmutexlock}

\func{wxMutexError}{Lock}{\void}

Locks the mutex object.

\wxheading{Return value}

One of:

\twocolwidtha{7cm}
\begin{twocollist}\itemsep=0pt
\twocolitem{{\bf MUTEX\_NO\_ERROR}}{There was no error.}
\twocolitem{{\bf MUTEX\_DEAD\_LOCK}}{A deadlock situation was detected.}
\twocolitem{{\bf MUTEX\_BUSY}}{The mutex is already locked by another thread.}
\end{twocollist}

\membersection{wxMutex::TryLock}\label{wxmutextrylock}

\func{wxMutexError}{TryLock}{\void}

Tries to lock the mutex object. If it can't, returns immediately with an error.

\twocolitem{{\bf MUTEX\_BUSY}}{The mutex is already locked by another thread.}
\end{twocollist}

\membersection{wxMutex::Unlock}\label{wxmutexunlock}

\func{wxMutexError}{Unlock}{\void}

Unlocks the mutex object.

\wxheading{Return value}

One of:

\twocolwidtha{7cm}
\begin{twocollist}\itemsep=0pt
\twocolitem{{\bf MUTEX\_NO\_ERROR}}{There was no error.}
\twocolitem{{\bf MUTEX\_DEAD\_LOCK}}{A deadlock situation was detected.}
\twocolitem{{\bf MUTEX\_BUSY}}{The mutex is already locked by another thread.}
\twocolitem{{\bf MUTEX\_UNLOCKED}}{The calling thread tries to unlock an unlocked mutex.}
