So it seams to be only 3 clib-function calls for each write operation.
I'm aware that this wouldn't be needed for Linux, but I just though add something... My Linux man page says that sigaction is a *system* call, and I would guess that it's the same on most Unixes -- indeed a quick google seems to indicate that this is also the case for SunOS/Solaris (at least the function is listed in the "system calls" section). System calls can be hideously expensive compared to regular C library function calls depending on architecture. -- Bardur Arantsson <bardurREMOVE@THISimada.sdu.dk> <bardurREMOVE@THISscientician.net> - That plot makes perfect sense.
