6 This function searches memory starting at @code{*@var{s}} for the
7 character @var{c}. The search only ends with the first occurrence of
8 @var{c}, or after @var{length} characters; in particular, a null
9 character does not terminate the search. If the character @var{c} is
10 found within @var{length} characters of @code{*@var{s}}, a pointer
11 to the character is returned. If @var{c} is not found, then @code{NULL} is
