-/*
- * Retrieve a list of matches with the current position.
- *
- * @mf
- * The matchfinder structure.
- * @in_begin
- * Pointer to the beginning of the input buffer.
- * @in_next
- * Pointer to the next byte in the input buffer to process. This is the
- * pointer to the sequence being matched against.
- * @min_len
- * Only record matches that are at least this long.
- * @max_len
- * The maximum permissible match length at this position.
- * @nice_len
- * Stop searching if a match of at least this length is found.
- * Must be <= @max_len.
- * @max_search_depth
- * Limit on the number of potential matches to consider. Must be >= 1.
- * @next_hash
- * Pointer to the hash code for the current sequence, which was computed
- * one position in advance so that the binary tree root could be
- * prefetched. This is an input/output parameter.
- * @best_len_ret
- * The length of the longest match found is written here. (This is
- * actually redundant with the 'struct lz_match' array, but this is easier
- * for the compiler to optimize when inlined and the caller immediately
- * does a check against 'best_len'.)
- * @lz_matchptr
- * An array in which this function will record the matches. The recorded
- * matches will be sorted by strictly increasing length and strictly
- * increasing offset. The maximum number of matches that may be found is
- * 'min(nice_len, max_len) - 3 + 1'.
- *
- * The return value is a pointer to the next available slot in the @lz_matchptr
- * array. (If no matches were found, this will be the same as @lz_matchptr.)
