void mysleep(int seconds) { struct timeval tv; tv.tv_sec=seconds; tv.tv_usec=0; select(0,NULL,NULL,NULL,&tv); } The code above should be portable to every platform that supports the standard select(2) semantics. It allows for subsecond precision too. This implementation isn't subject to signal dainbrammage either.
However, depending on your platform's implementation of select(), it may consume idle CPU cycles, causing an artificially high load figure and possibly stealing cycles from other lower-priority jobs. -- ---- phil stracchino ---- the renaissance man ---- lone geek biker ---- "I have a cat named Easter, he says, Will you ever learn - It's just an empty cage girl, if you kill the bird...." -- Tori Amos ---- "Oh, bother!" said Pooh, as Sheridan decompressed the airlock.... ----
