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

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
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.
