EXIT(3C)                COMMAND REFERENCE                EXIT(3C)



NAME
     exit - terminate a process

SYNOPSIS
     exit(status)
     int status;

     extern int lasterr

DESCRIPTION
     Exit terminates a process with the following consequences:

     All of the descriptors open in the calling process are
     closed.

     If the parent process of the calling process is executing a
     wait or is interested in the SIGCHLD signal, then it is
     notified of the calling process's termination and the low-
     order eight bits of status are made available to it; see
     wait(2). The low-order eight bits of status are available to
     the parent process.

     If the status given to exit is 0 or the status is not given,
     the status is replaced by the value of the last warning code
     given to the subroutine ERROR(3c). The value of this warning
     code is stored in the variable _last_err, and may be set by
     user programs in cases where ERROR cannot be used.

     The parent process ID of all of the calling process's
     existing child processes is also set to 1. This means that
     the initialization process (see intro(2)) inherits each of
     these processes as well.

RETURN VALUE
     This call never returns.

CAVEATS
     Programs that "fall off the end" (for example, do not
     explicitly call exit and do not explicitly return with a
     value) do not exit with any useful value.  In this cases,
     any exit code may result.

     Calling exit with no parameters causes the same action as
     calling exit with a value of 0.

SEE ALSO
     fork(2), wait(2), exit(2), ERROR(3c).
