- * glob_match - match a text string against a glob-style pattern
- * @text: the string to be examined
- * @pattern: the glob-style pattern to be matched against
- *
- * Either/both of text and pattern can be empty strings.
- *
- * Match text against a glob-style pattern, with wildcards and simple sets:
- *
- * ? matches any single character.
- * * matches any run of characters.
- * [xyz] matches a single character from the set: x, y, or z.
- * [a-d] matches a single character from the range: a, b, c, or d.
- * [a-d0-9] matches a single character from either range.
- *
- * The special characters ?, [, -, or *, can be matched using a set, eg. [*]
- * Behaviour with malformed patterns is undefined, though generally reasonable.
- *
- * Sample patterns: "SD1?", "SD1[0-5]", "*R0", "SD*1?[012]*xx"
- *
- * This function uses one level of recursion per '*' in pattern.
- * Since it calls _nothing_ else, and has _no_ explicit local variables,
- * this will not cause stack problems for any reasonable use here.
- *
- * RETURNS:
- * 0 on match, 1 otherwise.
