STRSIGNAL(3) Linux Programmer's Manual STRSIGNAL(3)
NAME
strsignal - return string describing signal
SYNOPSIS
#define_GNU_SOURCE
#include<string.h>
char*strsignal(int sig);
externconstchar*const sys_siglist[];
DESCRIPTION
The strsignal() function returns a string describing the signal number
passed in the argument sig. The string can only be used until the next
call to strsignal().
The array sys_siglist holds the signal description strings indexed by
signal number. The strsignal() function should be used if possible
instead of this array.
RETURNVALUE
The strsignal() 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 NULL pointer may be returned instead for
an invalid signal number.
CONFORMINGTO
This function is not part of any standard, but may be found on Linux
systems and some UNIX systems (such as Solaris).
