Sleep for a given number of milliseconds
Synopsis:
#include <unix.h>
unsigned int nap( unsigned int ms);
Arguments:
- ms
- The number of milliseconds that you want the process to sleep.
Library:
libc
Use the -l c option to
qcc
to link against this library.
This library is usually included automatically.
Description:
The nap() routine delays the calling process for ms
milliseconds.
This function is the same as
delay()
and is similar to
napms().
Note:
The suspension time may be greater than the requested amount, due to
the nature of time measurement (see the
“Understanding the Microkernel's Concept of Time”
chapter of the
QNX Neutrino Programmer's Guide), or due to
the scheduling of other, higher-priority threads by the system.
