See this description, which was part of the patch:

+	This function searches memory starting at <<*<[src]>>> for the
+	character <[c]>.  The search only ends with the first occurrence
+	of <[c]>; in particular, <<NUL>> does not terminate the search.
+	No bounds checking is performed, so this function should only
+	be used when it is certain that the character <[c]> will be found.

Cheers,
