+@deftypefn Supplemental void* memchr (const void *@var{s}, int @var{c}, @
+  size_t @var{n})
+
+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.
