+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
