pthread_condattr_getclock, pthread_condattr_setclock - get and set the clock selection condition variable attribute

cc -mt [ flag... ] file... [ library... ]
#include <pthread.h>

int pthread_condattr_getclock(
 const pthread_condattr_t *restrict attr,
 clockid_t *restrict clock_id);

int pthread_condattr_setclock(pthread_condattr_t *attr
 clockid_t clock_id);

The pthread_condattr_getclock() function obtains the value of the clock attribute from the attributes object referenced by attr. The pthread_condattr_setclock() function sets the clock attribute in an initialized attributes object referenced by attr. If pthread_condattr_setclock() is called with a clock_id argument that refers to a CPU-time clock, the call fails.

The clock attribute is the clock ID of the clock that is used to measure the timeout service of pthread_cond_timedwait(3C). The default value of the clock attribute refers to the system clock.

Upon successful completion, the pthread_condattr_getclock() function returns 0 and stores the value of the clock attribute of attr into the object referenced by the clock_id argument. Otherwise, an error number is returned to indicate the error.

Upon successful completion, the pthread_condattr_setclock() function returns 0. Otherwise, an error number is returned to indicate the error.

These functions may fail if: EINVAL

The pthread_condattr_setclock() function may fail if: EINVAL
