   1 \section{\class{wxMutexLocker}}\label{wxmutexlocker}
   2
   3 This is a small helper class to be used with \helpref{wxMutex}{wxmutex}
   4 objects. A wxMutexLocker acquires a mutex lock in the constructor and releases
   5 (or unlocks) the mutex in the destructor making it much more difficult to
   6 forget to release a mutex (which, in general, will promptly lead to the serious
   7 problems). See \helpref{wxMutex}{wxmutex} for an example of wxMutexLocker
   8 usage.

  22 \func{}{wxMutexLocker}{\param{wxMutex *}{mutex}}
  23
  24 Constructs a wxMutexLocker object associated with mutex which must be non NULL
  25 and locks it. Call \helpref{IsOk}{wxmutexisok} to check if the mutex was
  26 successfully locked.

  28 \membersection{wxMutexLocker::\destruct{wxMutexLocker}}\label{wxmutexlockerdtor}
  29 \func{}{\destruct{wxMutexLocker}}{\void}

  31 Destuctor releases the mutex if it was successfully acquired in the ctor.

  33 \membersection{wxMutexLocker::IsOk}\label{wxmutexlockerisok}
  34 \constfunc{bool}{IsOk}{\void}
  35
  36 Returns TRUE if mutex was acquired in the constructor, FALSE otherwise.
