-FUNCTION
-	<<memrchr>>---reverse search for character in memory
-
-INDEX
-	memrchr
-
-ANSI_SYNOPSIS
-	#include <string.h>
-	void *memrchr(const void *<[src]>, int <[c]>, size_t <[length]>);
-
-TRAD_SYNOPSIS
-	#include <string.h>
-	void *memrchr(<[src]>, <[c]>, <[length]>)
-	void *<[src]>;
-	void *<[c]>;
-	size_t <[length]>;
-
-DESCRIPTION
-	This function searches memory starting at <[length]> bytes
-	beyond <<*<[src]>>> backwards for the character <[c]>.
-	The search only ends with the first occurrence of <[c]>; in
-	particular, <<NUL>> does not terminate the search.
-
-RETURNS
-	If the character <[c]> is found within <[length]> characters
-	of <<*<[src]>>>, a pointer to the character is returned. If
-	<[c]> is not found, then <<NULL>> is returned.
-
-PORTABILITY
-<<memrchr>> is a GNU extension.
-
-<<memrchr>> requires no supporting OS subroutines.
