( Look closer (*), I agreed with you at the end of my previous reply. ) Sure, but if MSDN described spawn/exec the other way around, opengroup would win. For reference: From http://www.opengroup.org/onlinepubs/000095399/functions/exec.html: "The exec family of functions shall replace the current process image with a new process image. The new image shall be constructed from a regular, executable file called the new process image file. There shall be no return from a successful exec, because the calling process image is overlaid by the new process image." And on spawn: http://www.opengroup.org/onlinepubs/009695399/functions/posix_spawn.html "The posix_spawn() and posix_spawnp() functions shall create a new process (child process) from the specified process image. The new process image shall be constructed from a regular executable file called the new process image file." So to resume what Danny was saying, exec replaces, spawn doesn't.
