NAME

pthread_delay_np − Causes a thread to wait for a specified period of time before continuing execution. 

SYNOPSIS

#include <pthread.h>
int pthread_delay_np(

struct timespec ∗interval );

PARAMETERS

intervalNumber of seconds and nanoseconds that the calling thread waits before continuing execution. The value specified must be greater than or equal to 0. 

DESCRIPTION

This routine causes a thread to delay execution for a specified period of elapsed wall clock time. The period of time the thread waits is at least as long as the number of seconds and nanoseconds specified in the interval parameter. 

Specifying an interval of 0 seconds and 0 nanoseconds is allowed and can result in the thread giving up the processor or delivering a pending cancel. 

The struct timespec structure contains two fields, as follows:

       •tv.sec is an integer number of seconds, and

       •tv.nsec is an integer number of nanoseconds. 

RETURN VALUES

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