PTHREAD_MUTEX_INIT(3)  FreeBSD Library Functions Manual	 PTHREAD_MUTEX_INIT(3)

NAME
     pthread_mutex_init	-- create a mutex

SYNOPSIS
     #include <pthread.h>

     int
     pthread_mutex_init(pthread_mutex_t	*mutex,
	 const pthread_mutexattr_t *attr);

DESCRIPTION
     The pthread_mutex_init() function creates a new mutex, with attributes
     specified with attr.  If attr is NULL the default attributes are used,
     otherwise attr should be initialized by calling
     pthread_mutexattr_init(3).

     A mutex may also be initialized by	assignment with	the macro PTHREAD_MU-
     TEX_INITIALIZER.

RETURN VALUES
     If	successful, pthread_mutex_init() will return zero and put the new mu-
     tex ID into mutex,	otherwise an error number will be returned to indicate
     the error.

ERRORS
     pthread_mutex_init() will fail if:

     [EINVAL]		The value specified by attr is invalid.

     [ENOMEM]		The process cannot allocate enough memory to create
			another	mutex.

SEE ALSO
     pthread_mutex_destroy(3), pthread_mutex_lock(3), pthread_mutex_unlock(3),
