+ * Name: killpg
+ *
+ * Description:
+ *   The killpg() system call can be used to send any signal to process
+ *   group. See kill() for further information as this is just a simple
+ *   wrapper around the kill() function.
+ *
+ * Input Parameters:
+ *   pgrp  - The id of the process group to receive the signal.
+ *   signo - The signal number to send.  If 'signo' is zero, no signal is
+ *           sent, but all error checking is performed.
+ *
+ * Returned Value:
+ *    On success the signal was send and zero is returned. On error -1 is
+ *    returned, and errno is set one of the following error numbers:
+ *
+ *    EINVAL An invalid signal was specified.
+ *    EPERM  The thread does not have permission to send the
+ *           signal to the target thread.
+ *    ESRCH  No thread could be found corresponding to that
+ *           specified by the given thread ID
+ *    ENOSYS Do not support sending signals to process groups.
