SYNOPSIS

#include <pthread.h>
int pthread_mutexattr_init (pthread_mutexattr_t *attr);
int pthread_mutexattr_destroy (pthread_mutexattr_t *attr);
int pthread_mutexattr_setprioceiling (pthread_mutexattr_t *attr int prioceiling);
int pthread_mutexattr_getprioceiling (pthread_mutexattr_t *attr int *prioceiling);
int pthread_mutexattr_setprotocol (pthread_mutexattr_t *attr int protocol);
int pthread_mutexattr_getprotocol (pthread_mutexattr_t *attr int *protocol);
int pthread_mutexattr_settype (pthread_mutexattr_t *attr int type);
int pthread_mutexattr_gettype (pthread_mutexattr_t *attr int *type);

DESCRIPTION

Mutex attributes are used to specify parameters to pthread_mutex_init (.);
One attribute object can be used in multiple calls to pthread_mutex_init (,);
with or without modifications between calls.

The pthread_mutexattr_init ();
function initializes Fa attr with all the default mutex attributes.

The pthread_mutexattr_destroy ();
function destroys Fa attr .

The pthread_mutexattr_set (*);
functions set the attribute that corresponds to each function name.

The pthread_mutexattr_get (*);
functions copy the value of the attribute that corresponds to each function name to the location pointed to by the second function parameter.

RETURN VALUES

If successful, these functions return 0. Otherwise, an error number is returned to indicate the error.

ERRORS

The pthread_mutexattr_init ();
function will fail if:

Bq Er ENOMEM: Out of memory.

The pthread_mutexattr_destroy ();
function will fail if:

Bq Er EINVAL: Invalid value for Fa attr .

The pthread_mutexattr_setprioceiling ();
function will fail if:

Bq Er EINVAL: Invalid value for Fa attr , or invalid value for Fa prioceiling .

The pthread_mutexattr_getprioceiling ();
function will fail if:

Bq Er EINVAL: Invalid value for Fa attr .

The pthread_mutexattr_setprotocol ();
function will fail if:

Bq Er EINVAL: Invalid value for Fa attr , or invalid value for Fa protocol .

The pthread_mutexattr_getprotocol ();
function will fail if:

Bq Er EINVAL: Invalid value for Fa attr .

The pthread_mutexattr_settype ();
function will fail if:

Bq Er EINVAL: Invalid value for Fa attr , or invalid value for Fa type .

The pthread_mutexattr_gettype ();
function will fail if:

Bq Er EINVAL: Invalid value for Fa attr .

and pthread_mutexattr_destroy ();
functions conform to St -p1003.1-96
