pthread_...ttr_init(3) Library Functions Manual pthread_...ttr_init(3)
NAME
pthread_mutexattr_init, pthread_mutexattr_destroy - initialize and destroy a mutex attributes object
LIBRARY
POSIX threads library (libpthread, -lpthread)
SYNOPSIS
#include <pthread.h> int pthread_mutexattr_init(pthread_mutexattr_t *attr); int pthread_mutexattr_destroy(pthread_mutexattr_t *attr);
DESCRIPTION
The pthread_mutexattr_init() function initializes the mutex attributes object pointed to by attr with default values for all attributes defined by the implementation. The results of initializing an already initialized mutex attributes object are undefined. The pthread_mutexattr_destroy() function destroys a mutex attribute object (making it uninitialized). Once a mutex attributes object has been destroyed, it can be reinitialized with pthread_mutexattr_init(). The results of destroying an uninitialized mutex attributes object are undefined.
RETURN VALUE
On success, these functions return 0. On error, they return a positive error number.
STANDARDS
POSIX.1-2008.
HISTORY
POSIX.1-2001.
NOTES
Subsequent changes to a mutex attributes object do not affect mutex that have already been initialized using that object.
