millisecond delay in C - linux

[Macgyver]

Hi all,

does anyone know how to generate a millisecond delay in C, compiling
under Linux? I understand the function sleep() will generate a delay
down to a resolution of one second, but I need to be able to refine
this to milliseconds.

Any ideas?

Thanks in advance,

Ben.

checkout the select() call - it is often used for such a purpose. or
nanosleep().

Which part of the ISO C standard defines either of these functions?

There is no way to do so in standard C, the topic of this newsgroup. The
function sleep() is also not part of standard C. The clue is the fact that
the operating system is relevant.

Try asking in comp.unix.progr ammer <OT> or man 2 nanosleep </OT>.

Note that you seem to be asking for a way to achieve your solution ("How do
I use a sledgehammer to crack a walnut?"), not for a solution to your
problem ("How do I crack a walnut?"). This may well mean you don't get the
best end result.

Not the ISO C standard. Maybe Posix?

He doesnt want to use a sledgehammer (sleep), he wants a finer and
tinyer one (nanosleep) ;)
just kidding,

Take the advice about asking in a different newsgroup, because
there is *far* more to this than meets the eye.

In fact, you shouldn't ask in comp.unix.progr amming because the
discussion you need is specific to Linux, not unix in general,
though they won't throw a hissy fit about it like you get here.

Try comp.os.linux.m isc or better might be
comp.os.linux.d evelopment.apps .

1. POSIX isn't C. POSIX is an OS thing that has hooks originally
designed for C.

2. If it isn't ISO C, it's off-topic here. Try comp.programmin g.unix or
some such.

That was Joonas point. This group is about ISO C, the Posix, Unix and
Linux experts hang out in other groups where answers involving these
functions will get properly reviewed for errors.
