-FUNCTION
-        <<memchr>>---find character in memory
 
-INDEX
-        memchr
+@deftypefn Supplemental void* memchr (const void *@var{s}, int @var{c}, size_t @var{n})
 
-ANSI_SYNOPSIS
-        #include <string.h>
-        void *memchr(const void *<[src]>, int <[c]>, size_t <[length]>);
+This function searches memory starting at @code{*@var{s}} for the
+character @var{c}.  The search only ends with the first occurrence of
+@var{c}, or after @var{length} characters; in particular, a null
+character does not terminate the search.  If the character @var{c} is
+found within @var{length} characters of @code{*@var{s}}, a pointer
+to the character is returned.  If @var{c} is not found, then @code{NULL} is
+returned.
 
-TRAD_SYNOPSIS
-        #include <string.h>
-        void *memchr(<[src]>, <[c]>, <[length]>)
-        void *<[src]>;
-        void *<[c]>;
-        size_t <[length]>;
-
-DESCRIPTION
-        This function searches memory starting at <<*<[src]>>> for the
-        character <[c]>.  The search only ends with the first
-        occurrence of <[c]>, or after <[length]> characters; in
-        particular, <<NULL>> 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
-<<memchr>>  requires no supporting OS subroutines.
-
-QUICKREF
-        memchr ansi pure
