pthread_mutexattr_init(3P)

NAME
     pthread_mutexattr_init, pthread_mutexattr_destroy - initialize/destroy a
     mutex attribute object

C SYNOPSIS
     #include <pthread.h>

     int pthread_mutexattr_init(pthread_mutexattr_t *attr);
     int pthread_mutexattr_destroy(pthread_mutexattr_t *attr);

DESCRIPTION
     The function pthread_mutexattr_init() initializes the mutex attribute
     object referenced by attr to the default attribute values.  The default
     sharing value is PTHREAD_PROCESS_PRIVATE.  The default priority protocol
     is PTHREAD_PRIO_NONE.  The default mutex type is PTHREAD_MUTEX_DEFAULT.

     Once a mutex attribute object is used to initialize one or more mutexes,
     any function that affects the attribute object will not affect the
     previously initialized mutexes.  pthread_mutexattr_destroy()
     uninitializes the mutex attribute structure referenced by attr.

DIAGNOSTICS
     These functions return zero.
