Looking a bit harder, I noticed that it seems only to blow up if the original process exits before the child process. For example: main () { int pid = fork(); printf("after fork\n" ); if (pid) sleep(1); } This program always works, and if you change the (pid) to (!pid), it always fails. For a work-around, you can always wait for the child process before exiting the main process: main () { int s, p = fork(); printf("Hi\n" ); if (p) waitpid(p,&s,0); } --- Wade ---------- Wade Richards -= WRichard@Direct.CA =- "Never attribute to malice what can adequately be explained by stupidity." - For help on using this list, send a message to "gnu-win32-request@cygnus.com" with one line of text: "help".
