usleep(3) Library Functions Manual usleep(3)
NAME
usleep - Suspends execution for an interval of time
LIBRARY
Standard C Library (libc.so, libc.a)
SYNOPSIS
#include <unistd.h>
int usleep(
useconds_t useconds);
The following function declaration does not conform to current standards and is supported only for backward compatibility:
#include <unistd.h>
void usleep(
unsigned useconds);
STANDARDS
Interfaces documented on this reference page conform to industry standards as follows:
usleep(): XPG4-UNIX
Refer to the standards(5) reference page for more information about industry standards and associated tags.
PARAMETERS
Specifies the number of microseconds to sleep.
DESCRIPTION
The usleep() function suspends the current process from execution for the number of microseconds specified by the useconds parameter.
Because of other activity in the system, or because of the time spent in processing the call, the actual suspension time might be longer
than specified.
The useconds parameter must be less than 1,000,000. If the value of useconds is 0 (zero), the usleep() function has no effect.
In a multithreaded environment, the sleep() function is redefined to suspend the calling thread.
RETURN VALUES
On successful completion, the usleep() function returns 0 (zero). Otherwise, it returns -1 and sets errno to indicate the error.
ERRORS
The usleep() function sets errno to the specified values for the following conditions: The interval specified in the useconds parameter
exceeds 1,000,000 microseconds.
