.SH DESCRIPTION
|
2005-10-19 07:07:02 +00:00
|
|
|
The \fBstrsignal\fP() function returns a string describing the signal
|
2004-11-03 13:51:07 +00:00
|
|
|
number passed in the argument \fIsig\fP. The string can only be used
|
2005-10-19 07:07:02 +00:00
|
|
|
until the next call to \fBstrsignal\fP().
|
2004-11-03 13:51:07 +00:00
|
|
|
.PP
|
|
|
|
The array \fIsys_siglist\fP holds the signal description strings
|
2005-10-19 07:07:02 +00:00
|
|
|
indexed by signal number. The \fBstrsignal\fP() function should be
|
2004-11-03 13:51:07 +00:00
|
|
|
used if possible instead of this array.
|
|
|
|
.SH "RETURN VALUE"
|
2005-10-19 07:07:02 +00:00
|
|
|
The \fBstrsignal\fP() function returns the appropriate description
|
2004-11-03 13:51:07 +00:00
|
|
|
string, or an unknown signal message if the signal number is invalid.
|
2005-10-19 13:48:50 +00:00
|
|
|
On some systems (but not on Linux), a NULL pointer may be
|
2004-11-03 13:51:07 +00:00
|
|
|
returned instead for an invalid signal number.
|
|
|
