14 \fBvoid\fR(\fB*ssignal\fR (\fBint\fR \fIsig\fR, \fBint\fR (*\fIaction\fR)(\fBint\fR)))(\fBint\fR);
33 \fIaction\fR, with the software signal \fIsig\fR; the software signal,
35 causes the action established for that signal to be taken.
39 signal for which an action is to be established. The second argument defines
40 the action; it is either the name of a (user-defined) \fIaction\fR
42 \fBSIG_IGN\fR (ignore). The \fBssignal()\fR function returns the action
43 previously established for that signal type; if no action has been established
51 If an action function has been established for \fIsig\fR, then that action is
52 reset to \fBSIG_DFL\fR and the action function is entered with argument
54 action function.
57 If the action for \fIsig\fR is \fBSIG_IGN\fR, \fBgsignal()\fR returns the value
58 1 and takes no other action.
61 If the action for \fIsig\fR is \fBSIG_DFL\fR, \fBgsignal()\fR returns the value
62 0 and takes no other action.
65 If \fIsig\fR has an illegal value or no action was ever specified for
66 \fIsig\fR, \fBgsignal()\fR returns the value 0 and takes no other action.
