     Two provisions I'm familiar with:

     Under Xenix there is a nap() system call. It takes an argument in
milliseconds, but the granularity depends on the system tick rate.
To use it the -lx (to link the xenix library) is required.

     Under Sun OS, usleep(), which takes an argument in microseconds
is available. I don't remember having to do anything special to use it but
it's been awhile.
