PTHREAD_MUTEX_INIT(3)   NetBSD Library Functions Manual  PTHREAD_MUTEX_INIT(3)

NAME
     pthread_mutex_init -- create a mutex

LIBRARY
     POSIX Threads Library (libpthread, -lpthread)

SYNOPSIS
     #include <pthread.h>

     int
     pthread_mutex_init(pthread_mutex_t * restrict mutex,
         const pthread_mutexattr_t * restrict 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.

RETURN VALUES
     If successful, pthread_mutex_init() will return zero and put the new
     mutex id into mutex, otherwise an error number will be returned to indi-
     cate the error.

ERRORS
     pthread_mutex_init() shall fail if:

     [EAGAIN]           The system lacks the resources to initialize another
                        mutex.

     [ENOMEM]           The process cannot allocate enough memory to initial-
                        ize another mutex.

     pthread_mutex_init() may fail if:

     [EINVAL]           The value specified by attr is invalid.

     pthread_mutex_destroy(3), pthread_mutex_lock(3),
     pthread_mutex_trylock(3), pthread_mutex_unlock(3)

STANDARDS
     pthread_mutex_init() conforms to ISO/IEC 9945-1:1996 (``POSIX.1'').
