    NAME

    killpg - send signal to a process group
     
    

    SYNOPSIS

    #include <signal.h>
    
    int killpg(pid_t pgrp, int sig);
    

     

    DESCRIPTION

    The killpg() function sends the signal sig to the process group pgrp. See signal.h(3HEAD) for a list of signals.

    The real or effective user ID of the sending process must match the real or saved set-user ID of the receiving process, unless the effective user ID of the sending process is the privileged user. A single exception is the signal SIGCONT, which may always be sent to any descendant of the current process.  

    RETURN VALUES

    Upon successful completion, 0 is returned. Otherwise, -1 is returned and errno is set to indicate the error.  

    ERRORS

    The killpg() function will fail and no signal will be sent if:

    EINVAL

    The sig argument is not a valid signal number.

    EPERM

    The effective user ID of the sending process is not privileged user, and neither its real nor effective user ID matches the real or saved set-user ID of one or more of the target processes.

    ESRCH

    No processes were found in the specified process group.
