.SH "CONTEXT"
.PP
The signal\*(Aqs sender\&. (correct?)
.SH "DESCRIPTION"
.PP
Possible __group_send_sig_info and specific_send_sig_info return values are as follows;
.PP
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\&.
.PP
\-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
\fBkill\fR\&.
.PP
Possible send_group_sigqueue and send_sigqueue return values are as follows;
.PP
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)\&.
.PP
1 \-\- The signal was ignored by the receiving process\&.
.PP
\-1 \-\- (send_sigqueue only) The task was marked exiting, allowing * posix_timer_event to redirect it to the group leader\&.
