DESCRIPTION         top

       Possible __group_send_sig_info and specific_send_sig_info return
       values are as follows;

       0 -- The signal is successfully sent to a process, which means
       that, (1) the signal was ignored by the receiving process, (2)
       this is a non-RT signal and the system already has one queued,
       and (3) the signal was successfully added to the sigqueue of the
       receiving process.

       -EAGAIN -- The sigqueue of the receiving process is overflowing,
       the signal was RT, and the signal was sent by a user using
       something other than kill.

       Possible send_group_sigqueue and send_sigqueue return values are
       as follows;

       0 -- The signal was either successfully added into the sigqueue
       of the receiving process, or a SI_TIMER entry is already queued
       (in which case, the overrun count will be simply incremented).

       1 -- The signal was ignored by the receiving process.

       -1 -- (send_sigqueue only) The task was marked exiting, allowing
       * posix_timer_event to redirect it to the group leader.
