pthread_get_expiration_np - Obtains a value representing a
desired expiration time
const struct timespec *delta,
struct timespec *abstime );
DECthreads POSIX 1003.1c Library (libpthread.so)
Number of seconds and nanoseconds to add to the current
system time. (The result is the time in the future.) This
result will be placed in abstime. Value representing the
absolute expiration time. The absolute expiration time is
obtained by adding delta to the current system time. The
resulting abstime is in Universal Coordinated Time (UTC).
This routine adds a specified interval to the current
absolute system time and returns a new absolute time. This
new absolute time is used as the expiration time in a call
The timespec structure contains the following two fields:
tv_sec is an integral number of seconds. tv.nsec is an
integral number of nanoseconds.
If an error condition occurs, this routine returns an
integer value indicating the type of error. Possible
return values are as follows: Successful completion. The
value specified by delta is invalid.
