Get the clock attribute from a condition-variable attribute object
#include <pthread.h>
int pthread_condattr_getclock(
const pthread_condattr_t * attr,
clockid_t * id );
- 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.

to link against this library.
This library is usually included automatically.
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.
- EOK
- Success.
- EINVAL
- Invalid value attr.
