\func{}{wxSemaphore}{\param{int }{initialcount = 0}, \param{int }{maxcount = 0}}
Specifying a {\it maxcount} of $0$ actually makes wxSemaphore behave as if
there is no upper limit. If maxcount is $1$, the semaphore behaves exactly as a
mutex.
there is no upper limit. If maxcount is $1$, the semaphore behaves almost as a
mutex (but unlike a mutex it can be released by a thread different from the one
which acquired it).
{\it initialcount} is the initial value of the semaphore which must be between
$0$ and {\it maxcount} (if it is not set to $0$).
