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);

       extern const char * 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.

RETURN VALUE
       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.

CONFORMING TO
       POSIX.1-2008.  Present on Solaris and the BSDs.
