/*
FUNCTION
<<strsignal>>---convert signal number to string
INDEX
strsignal
ANSI_SYNOPSIS
#include <string.h>
char *strsignal(int <[signal]>);
TRAD_SYNOPSIS
#include <string.h>
char *strsignal(<[signal]>)
int <[signal]>;
DESCRIPTION
<<strsignal>> converts the signal number <[signal]> into a
string. If <[signal]> is not a known signal number, the result
will be of the form "Unknown signal NN" where NN is the <[signal]>
is a decimal number.
RETURNS
This function returns a pointer to a string. Your application must
not modify that string.
PORTABILITY
POSIX.1-2008 C requires <<strsignal>>, but does not specify the strings used
for each signal number.
<<strsignal>> requires no supporting OS subroutines.
QUICKREF
strsignal pure
