@deftypefn Supplemental void* memchr (const void *@var{s}, int @var{c}, @

|
|
|
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.
