strsignal - return string describing signal
Návod, kniha: Linux Programmer's Manual
#define _GNU_SOURCE
#include <string.h>
char *strsignal(int sig);
extern const char * const sys_siglist[];
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.
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.
This function is not part of any standard, but may be found on Linux systems and
some UNIX systems (such as Solaris).
