NAME

     strsignal - return string describing signal

SYNOPSIS

     #include <string.h>

     char *strsignal(int sig);

     extern const char * const sys_siglist[];

 Feature Test Macro Requirements for glibc (see feature_test_macros(7)):

     strsignal():
         Since glibc 2.10:
             _POSIX_C_SOURCE >= 200809L
         Before glibc 2.10:
             _GNU_SOURCE

DESCRIPTION

     The  strsignal() function returns a string describing the signal number
     passed in the argument sig.  The string can be used only 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), NULL may instead be returned for an invalid
     signal number.
