   (1) the signal was ignored by the receiving process,

   (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

   Possible send_group_sigqueue and
   send_sigqueue return values are as follows;
   </p><p>

   0 -- The signal was either sucessfully 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).

   </p><p>

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