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.
