Timer functions for DOS box program?

[Dave]

I have a program written in C that needs a way to run a function every
second or two (resolution 100 mS). The program is a console program.
What I would like is likely a DOS API that allows a sleep for a
period of time so that other operations on the computer are not
disturbed. I have looked through a few books, the web, and news
groups, but have not found a solution. I recall a number of DOS
programs, such as games and terminal programs, that used similar
functionality. Any suggestions?

Portability is not a big issue in that it is a DOS program always, but
that said, there may be differences between the versions of DOS and
Windows that will need to be tested in code.

Standard C has no good way to do this. You said you're looking for a
DOS API; you'll have better luck finding it in a system-specific
newsgroup.

comp.os.msdos.programmer *might* be the best place to ask, but that's
based only on the name of the group. Take a look at the existing
articles first, and find out if they have an FAQ list.

At one time that was a very active group, but not any more. MS has lots of
public news groups available. Set you're news reader to server:
