Initializes a static mutex with default attributes.
Threads Library (libpthreads.a)
static pthread_mutex_t mutex = PTHREAD_MUTEX_INITIALIZER;
The PTHREAD_MUTEX_INITIALIZER macro initializes the static mutex mutex, setting its attributes to default values. This macro should only be used for static mutexes, as no error checking is performed.
Note: The pthread.h header file must be the first included file of each source file using the threads library. Otherwise, the -D_THREAD_SAFE compilation flag should be used, or the cc_r compiler used. In this case, the flag is automatically set.
This macro is part of the Base Operating System (BOS) Runtime.
The pthread_mutex_init subroutine.
