—
create a mutex
#include

int
pthread_mutex_init
(pthread_mutex_t

The
pthread_mutex_init
()
function creates a new mutex, with attributes specified with
attr. If attr is NULL the
default attributes are used.
If successful, pthread_mutex_init
() will
return zero and put the new mutex id into mutex,
otherwise an error number will be returned to indicate the error.
The pthread_mutex_init
() function will
fail if:
pthread_mutex_destroy(3), pthread_mutex_lock(3), pthread_mutex_trylock(3), pthread_mutex_unlock(3), pthread_mutexattr(3)
The pthread_mutex_init
() function conforms
to ISO/IEC 9945-1:1996
(“POSIX.1”).
