pthread_condattr_getclock()

Get the clock attribute from a condition-variable attribute object

Synopsis:

#include <pthread.h>

int pthread_condattr_getclock( 
                     const pthread_condattr_t * attr,
                     clockid_t * id );

Arguments:

attr

A pointer to the pthread_condattr_t object from which you want to get the clock.

id

A pointer to a clockid_t object where the function can store the clock ID.

Library:

libc

Use the -l c option to qcc to link against this library. This library is usually included automatically.

Description:

The pthread_condattr_getclock() function obtains the value of the clock attribute from the attributes object referenced by attr.

The clock attribute is the clock ID of the clock that's used to measure the timeout service of pthread_cond_timedwait(). The default value of the clock attribute refers to the system clock.

Returns:

Success.

EINVAL

Invalid value attr.
