The programmer explicitly has to call exec() after a > vfork(). right? right, vfork() isn't a combination of fork() and exec(), more exactly, it's a version of fork() to be used only when immediatly followed by a exec() so, instead of writing if (! fork ()) exec (...); you could write if (! vfork ()) exec (...); and avoid the copying of the process segment that would be overwritten by exec(). in modern OSs, the process is marked copy-on-write, so it's just as fast, without the restrictions. that's why it's man page tells you not to use it anymore. - ------ Javier -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.1 (GNU/Linux) iD8DBQE+Rn3HsIoGnxsRK/ERAmzmAJ0YLEju/TRGLnX8asM3vEN/MgMVXQCgpdUL B4WhKo2sgxVbxDkGq/QPbLo= =Bxlb -----END PGP SIGNATURE----- -- Kernelnewbies: Help each other learn about the Linux kernel.
