pthread_m...attr_init(3) Library Functions Manualpthread_m...attr_init(3)

NAME        top

       pthread_mutexattr_init, pthread_mutexattr_destroy - initialize and       destroy a mutex attributes object

LIBRARY        top

       POSIX threads library (libpthread,-lpthread)

SYNOPSIS        top

#include <pthread.h>int pthread_mutexattr_init(pthread_mutexattr_t *attr);int pthread_mutexattr_destroy(pthread_mutexattr_t *attr);

DESCRIPTION        top

       Thepthread_mutexattr_init() function initializes the mutex       attributes object pointed to byattr with default values for all       attributes defined by the implementation.       The results of initializing an already initialized mutex       attributes object are undefined.       Thepthread_mutexattr_destroy() function destroys a mutex       attribute object (making it uninitialized).  Once a mutex       attributes object has been destroyed, it can be reinitialized withpthread_mutexattr_init().       The results of destroying an uninitialized mutex attributes object       are undefined.

RETURN VALUE        top

       On success, these functions return 0.  On error, they return a       positive error number.

STANDARDS        top

       POSIX.1-2008.

HISTORY        top

       POSIX.1-2001.

NOTES        top

       Subsequent changes to a mutex attributes object do not affect       mutex that have already been initialized using that object.
