sleep()

[Dave]

For the life of me, I thought there was a sleep() function in the Standard
Library (or something similarly named), but I can't find it. Is it
non-existent or, if not, what header is it in?

Thanks!

There is no such thing.

It isn't standard C - it's POSIX, I believe, which is not the same
thing.

There is not the concept of threads in C++98. It is considered a system
extension. You have to check the manual of your compiler.

SLEEP(3) Linux Programmer’s Manual SLEEP(3)

NAME
sleep - Sleep for the specified number of seconds

SYNOPSIS
#include <unistd.h>

unsigned int sleep(unsigned int seconds);

DESCRIPTION
sleep() makes the current process sleep until seconds seconds
have elapsed or a signal arrives which is not ignored.

RETURN VALUE
Zero if the requested time has elapsed,
or the number of seconds left to sleep.

CONFORMING TO
POSIX.1

BUGS
sleep() may be implemented using SIGALRM;
mixing calls to alarm() and sleep() is a bad idea.

Using longjmp() from a signal handler or modifying the handling
of SIGALRM while sleeping will cause undefined results.

SEE ALSO
signal(2), alarm(2)

True, but what has that to do with the (equally non-standard,
hypothetical) sleep() function?
