The string can only be used +until the next call to \fBstrsignal()\fP. +.PP +The array \fIsys_siglist\fP holds the signal description strings +indexed by signal number. The \fBstrsignal()\fP function should be +used if possible instead of this array. +.SH "RETURN VALUE" +The \fBstrsignal()\fP function returns the appropriate description +string, or an unknown signal message if the signal number is invalid. +On some systems (but not on Linux), a \fBNULL\fP pointer may be +returned instead for an invalid signal number. +.SH "CONFORMING TO" +This function is not part of any standard, but may be found on Linux +systems and some UNIX systems (such as Solaris). +.SH "SEE ALSO" +.BR psignal (3), +.BR strerror (3) |
