pthread_condattr_setclock()

Initialize condition variable

Synopsis:

#include <pthread.h>

int pthread_condattr_setclock( 
                     pthread_condattr_t * attr, 
                     clockid_t * id );

Library:

libc

Description:

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

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:

Zero on success, or an error number to indicate the error.

Errors:

EINVAL

Invalid value attr.

Classification:

POSIX 1003.1j (draft)
