NAME
get_expiration_time() - add a specific time interval to the current absolute system time
SYNOPSIS
#include <time.h>
int get_expiration_time(
struct timespec *delta,
struct timespec *abstime
);
DESCRIPTION
The get_expiration_time()
function adds a specific time interval to the current absolute system
time and returns the new absolute time. This new absolute time is used as the expiration time in a call to
pthread_cond_timedwait (3T).
The delta argument represents the number of seconds and nanoseconds to add to the current system
time. On return from this function, the abstime argument contains the absolute system time that will be
used in a call to pthread_cond_timedwait(3T).
Parameters
delta Number of seconds and nanoseconds to add to the current system time.
abstime Output parameter for the absolute system time after adding delta to the current absolute
system time.
RETURN VALUE
Upon successful completion,
get_expiration_time()
returns zero. Otherwise, an error number is
returned to indicate the error (the
errno variable is not set).
ERRORS
If any of the following occur, the
get_expiration_time()
function returns the corresponding error
number:
[EINVAL] The value specified by delta or abstime is invalid.
