.SH DESCRIPTION
|
2007-05-12 09:06:04 +00:00
|
|
|
The
|
|
|
|
.BR strsignal ()
|
|
|
|
function returns a string describing the signal
|
2007-04-12 22:42:49 +00:00
|
|
|
number passed in the argument \fIsig\fP.
|
|
|
|
The string can only be used
|
2007-05-12 09:06:04 +00:00
|
|
|
until the next call to
|
|
|
|
.BR strsignal ().
|
2004-11-03 13:51:07 +00:00
|
|
|
.PP
|
|
|
|
The array \fIsys_siglist\fP holds the signal description strings
|
2007-04-12 22:42:49 +00:00
|
|
|
indexed by signal number.
|
2007-05-12 09:06:04 +00:00
|
|
|
The
|
|
|
|
.BR strsignal ()
|
|
|
|
function should be
|
2004-11-03 13:51:07 +00:00
|
|
|
used if possible instead of this array.
|
|
|
|
.SH "RETURN VALUE"
|
2007-05-12 09:06:04 +00:00
|
|
|
The
|
|
|
|
.BR strsignal ()
|
|
|
|
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.
