-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{src} 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{src}, a pointer
+to the character is returned. If @var{c} is not found, then NULL is
+returned.
