NAME

pthread_get_expiration_np − Obtains a value representing a desired expiration time. 

SYNOPSIS

#include <pthread.h>
int pthread_get_expiration_np(

struct timespec ∗delta ,
struct timespec ∗abstime );

PARAMETERS

deltaNumber of seconds and nanoseconds to add to the current system time.  The result is the time that a timed wait expires. 

abstimeValue representing the expiration time. 

DESCRIPTION

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 to pthread_cond_wait. 

The truct timespec structure contains the following two fields:

       •tv.sec is an integer number of seconds

       •tv.nsec is an integer number of nanoseconds

RETURN VALUES

If an error condition occurs, this routine returns −1 and errno is set to the corresponding error value. Possible return values are as follows:
