PTHREAD_MUTEX_INIT(3) BSD 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 *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 indicate the error. ERRORS
pthread_mutex_init() will fail if: [EAGAIN] The system temporarily lacks the resources to create another mutex. [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_trylock(3), pthread_mutex_unlock(3) STANDARDS
pthread_mutex_init() conforms to ISO/IEC 9945-1:1996 (``POSIX.1''). BSD
