NAME
strsignal -- map a signal number to a signal message string
SYNOPSIS
char *strsignal (int signo)
DESCRIPTION
Maps an signal number to an signal message string, the contents of
which are implementation defined. On systems which have the external
variable sys_siglist, these strings will be the same as the ones used
by psignal().
If the supplied signal number is within the valid range of indices
for the sys_siglist, but no message is available for the particular
signal number, then returns the string "Signal NUM", where NUM is the
signal number.
If the supplied signal number is not a valid index into sys_siglist,
returns NULL.
The returned string is only guaranteed to be valid only until the
next call to strsignal.
Also, though not declared "const", it is.
