- * Calculate min_str and max_str that ranges a LIKE string.
- * Arguments:
- * ptr		IN: Pointer to LIKE string.
- * ptr_length	IN: Length of LIKE string.
- * escape	IN: Escape character in LIKE.  (Normally '\').
- *		No escape characters should appear in min_str or max_str
- * res_length   IN: Length of min_str and max_str.
- * min_str      IN/OUT: Smallest case sensitive string that ranges LIKE.
- *		Should be space padded to res_length.
- * max_str	IN/OUT: Largest case sensitive string that ranges LIKE.
- *		Normally padded with the biggest character sort value.
- * min_length	OUT: Length of min_str without space padding.
- * max_length	OUT: Length of max_str without space padding.
- *
- * The function should return 0 if ok and 1 if the LIKE string can't be
- * optimized !
