Hi everybody,
I am awfully new to programming in C and all I have had to work with
so far have been tutorials that I've found online. In my searching,
however, I have not found a solution to a problem I have been facing.
Ideally, I would like the program to wait 5 minutes before executing
the rest of the code. Is there some way that I can use time.h and just
run a for loop that waits until 5 minutes has passed to continue down
the program?
Any help that you experts could give would be greatly appreciated.
Also, I apologize in advance if there is an obvious solution I have
overlooked.
Thanks,
Dave

GNU C is not ISO standard C. Extensions are off-topic here. There
would have been no objection if you had made this clear.
He did make it very clear that this is in the GNU C library. How could it
possibly get any clearer?
The GNU C library also has a strlen function.
http://www.gnu.org/software/libc/man...ng-Length.html
So what? Does that make strlen off topic here?
Of course not.
Sorry, apparently I wasn't as clear as I thought I was. My point is
that saying that the GNU C library has a sleep function does not by
itself make it perfectly clear that the sleep function is
non-standard.
The GNU C library provides implementations of both sleep() and
strlen(). strlen() is topical here; sleep() is not (though a brief
mention of sleep() with a redirection to a more appropriate forum is
IMHO perfectly ok).

No. But 'sleep' is off-topic. Have you caught on to the
difference yet?

This is, of course, portable only to systems that provide a command
called "sleep" that does what you expect it to do.

Of course I do and did. I was only pointing out that Ivan clearly stated
where his sleep is from.
Nothing else.

Wonder what effect that would have on systems:
a) That have no sleep command
b) That have a sleep, but the parameter is in minutes
c) That have a sleep, but the parameter is in milliseconds
d) That have a sleep, but the parameter is a resource or device ID and
sleep waits for the resource to become available
FWIW, Windows XP - arguably the most populous desktop OS - seems to have
no bundled sleep command.
Not sure what you mean by bundled but the Windows API has a Sleep() function
that has been available at least since Windows 95.

Please don't top-post (corrected here).
A Sleep() function is not the same as a "sleep" command.

Besides which, there is a major distinction between a sleep command
and a sleep function.
There is a sleep command on my Windows machine, because I wrote it.
But for most Windows systems, if you execute this code snippet:
system("sleep 300");
there won't be any 3 second pause.

Explain to us how to invoke the Sleep() function, in a standard XP box,
using the code above.
Oh, right, you don't. XP has no sleep command, exactly as I said. This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics | |
