17 The strsignal() function returns a string describing the signal number
18 passed in the argument sig. The string can only be used until the next
19 call to strsignal().
20
21 The array sys_siglist holds the signal description strings indexed by
22 signal number. The strsignal() function should be used if possible
23 instead of this array.
24
26 The strsignal() function returns the appropriate description string, or
27 an unknown signal message if the signal number is invalid. On some
28 systems (but not on Linux), a NULL pointer may be returned instead for
29 an invalid signal number.

32 This function is not part of any standard, but aside from Linux, it can
33 be found on Solaris and the BSDs.
