NAME

       nbd_kill_subprocess - kill server running as a subprocess

SYNOPSIS

        #include <libnbd.h>

        int nbd_kill_subprocess (struct nbd_handle *h, int signum);

DESCRIPTION

       This call may be used to kill the server running as a subprocess that was previously
       created using nbd_connect_command(3).  You do not need to use this call.  It is only
       needed if the server does not exit when the socket is closed.

       The "signum" parameter is the optional signal number to send (see signal(7)).  If "signum"
       is 0 then "SIGTERM" is sent.

RETURN VALUE

       If the call is successful the function returns 0.

ERRORS

       On error "-1" is returned.

       Refer to "ERROR HANDLING" in libnbd(3) for how to get further details of the error.

       The following parameters must not be NULL: "h".  For more information see "Non-NULL
       parameters" in libnbd(3).

VERSION
