val make_pattern : string -> pattern
(* Prepares the passed pattern *)
val find_pattern : pattern -> ?pos:int -> ?len:int -> string -> int
(* Searches the position where the pattern or a prefix of the pattern
* occurs in the substring from position [pos] to [pos+len-1].
* Possible return values p:
* - pos <= p <= pos+len-length(pattern):
* The pattern occurs at position p in the string, i.e.
* string.[p+k] = pattern.[k], for all 0 <= k < length(pattern).
* Furthermore, the returned position p is the first such position.
* - pos+len-length(pattern) < p < pos+len
* The string ends with a prefix of the pattern, i.e.
* string.[p+k] = pattern[k], for all 0 <= k < pos+len-p.
* - p = pos+len
* Neither does the pattern occur in the string, nor is the
* (non-empty) suffix of the string a prefix of the pattern.
*
* Defaults:
* ~pos = 0
* ~len = length(string)-pos = "until the end of the string"
