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

       This  function is not part of any standard, but may be found on Linux systems and some UNIX systems (such
       as Solaris).
