Try extracting usleep.o from BSD's libc.a and using it under Ultrix!
Or get the source and recompile.

?I thought Ultrix used BSD as its porting base, so what happened ?

Probably 4.2 vs 4.3.

?Anyway can someone tell me what to use on Ultrix and probably SysV 
?in place of  usleep() ?

Usleep is just a wrapper around setitimer. The key word is "just",
as it must coexist with any previous use of itimers.

You can also use select with a subsecond sleep.

I don't think System V Release 3 has a subsecond sleep. Probably in SVR4.
