delay() function with gcc on Linux?
Marc O. Gloor
Hello,
I'm looking for a function like delay() which is part of the
Borland C compiler under DOS. Under Linux, I can't find an
equal function?
Including <asm/delay.h> and the delay() function doesn't work
correctly with my gcc on GNU/Linux 2.0.
Does anybody can help me?

sleep(3) is the recommended (portable) solution. nanosleep(2) has a more
finegrained resolution, but is less portable.

On modern Linux system, as an application programmer you should never have
to include headers in <asm/*>, unless you really, really know what you are
doing. <asm/*> is kernel-specific.

that this is a system library function. Posting to a linux group
might get you some insight as to how the delay() function works,
as might trying
man -s 2 delay
The compiler has nothing to do with how the delay function works.
