int kjb_waitpid(pid_t pid);

DESCRIPTION

The routine kjb_waitpid waits until a specified child process terminates or a signal is received (by the process doing the waiting). Unlike the typical system waitpid(), if the process only changes state, this routine continues waiting. Once the child process terminates, then NO_ERROR is returned. If the reason for termination is required, then the routine kjb_waitpid2 should be used. If the waiting process is interrupted during the wait, then INTERRUPTED is returned instead.

RETURNS

If the child process terminates, then NO_ERROR is returned. If a signal interrupts the wait, then INTERRUPTED is returned. ERROR may be returned if there is a problem with the call.

NOTES

See check_child/check_child2 for similar capability that has an immediate return.
