Obtains a value representing a desired expiration time.
Threads Library (libpthreads.a)
#include <pthread.h>
int pthread_get_expiration_np (delta, abstime) struct timespec *delta; struct timespec *abstime;
The pthread_get_expiration_np subroutine adds the interval delta to the current absolute system time and returns a new absolute time. This new absolute time can be used as the expiration time in a call to the pthread_cond_timedwait subroutine.
Notes:
delta | Points to the time structure specifying the interval. |
abstime | Points to where the new absolute time will be stored. |
Upon successful completion, the new absolute time is returned via the abstime parameter, and 0 is returned. Otherwise, an error code is returned.
The pthread_get_expiration_np subroutine is unsuccessful if the following is true:
EINVAL | The delta or abstime parameters are not valid. |
This subroutine is part of the Base Operating System (BOS) Runtime.
This subroutine is not POSIX compliant and is provided only for compatibility with DCE threads. It should not be used when writing new applications.
