|
|
|
|
+to the process whose PID is given in

|
|
|

+The null signal (0) can be used to check if a process with a given

|
|
|
+.PP
|
|
|
|
+The
|

|
|
|
|
+field of the
|
|
|
|
+.I siginfo_t
|
|
|
|
+structure passed as the second argument to the handler.
|
|
|
|
+Furthermore, the
|
|
|

+.I si_code
|
|
|
|
+field of that structure will be set to
