i'm playing with a sample program to make direct system calls as described here: http://www.ibm.com/developerworks/linux/library/l-system-calls/ and i've written a trivial program that should theoretically work, but the compilation fails on the line invoking _syscall0(). where is that macro defined in user space? rday -- ======================================================================== Robert P.
