(as decided and > controlled by glibc) Not sure about the function's name, but I was just guessing it should "return" back to user space as either signal or exception. However, in the case of int 3 (breakpoint), you need to return to the "controller", because most likely you need to inspect something in the traced process. This process will return working normally after the patched instruction is restored (i.e int 3 is removed and original instruction is copied back) somebody CMIIW... regards, Mulyadi -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
