SYNOPSIS

17       strsignal():
18           Since glibc 2.10:
19               _POSIX_C_SOURCE >= 200809L
20           Before glibc 2.10:
21               _GNU_SOURCE

DESCRIPTION

24       The  strsignal() function returns a string describing the signal number
25       passed in the argument sig.  The string can be used only until the next
26       call to strsignal().
27
28       The  array  sys_siglist holds the signal description strings indexed by
29       signal number.  The strsignal() function should  be  used  if  possible
30       instead of this array.
31

RETURN VALUE

33       The strsignal() function returns the appropriate description string, or
34       an unknown signal message if the signal number  is  invalid.   On  some
35       systems (but not on Linux), NULL may instead be returned for an invalid
36       signal number.
