00066  * Try to match the string to the given pattern, return APR_SUCCESS if

00068  *    an illegal pattern.
00069  *
00070  * With all flags unset, a pattern is interpreted as such:
00071  *
00072  * PATTERN: Backslash followed by any character, including another
00073  *          backslash.<br/>
00074  * MATCHES: That character exactly.
00075  * 
00076  * <p>
00077  * PATTERN: ?<br/>
00078  * MATCHES: Any single character.
00079  * </p>
00080  * 
00081  * <p>
00082  * PATTERN: *<br/>
00083  * MATCHES: Any sequence of zero or more characters. (Note that multiple
00084  *          *s in a row are equivalent to one.)
00085  * 
00086  * PATTERN: Any character other than \?*[ or a \ at the end of the pattern<br/>
00087  * MATCHES: That character exactly. (Case sensitive.)
00088  * 
00089  * PATTERN: [ followed by a class description followed by ]<br/>
00090  * MATCHES: A single character described by the class description.
00091  *          (Never matches, if the class description reaches until the
00092  *          end of the string without a ].) If the first character of
00093  *          the class description is ^ or !, the sense of the description
00094  *          is reversed.  The rest of the class description is a list of
00095  *          single characters or pairs of characters separated by -. Any
00096  *          of those characters can have a backslash in front of them,
00097  *          which is ignored; this lets you use the characters ] and -
00098  *          in the character class, as well as ^ and ! at the
00099  *          beginning.  The pattern matches a single character if it
00100  *          is one of the listed characters or falls into one of the
00101  *          listed ranges (inclusive, case sensitive).  Ranges with
00102  *          the first character larger than the second are legal but
00103  *          never match. Edge cases: [] never matches, and [^] and [!]
00104  *          always match without consuming a character.
00105  * 
00106  * Note that these patterns attempt to match the entire string, not
00107  * just find a substring matching the pattern.
00108  *
00109  * @param pattern The pattern to match to
00110  * @param strings The string we are trying to match
00111  * @param flags flags to use in the match.  Bitwise OR of:
00112  * <pre>
00113  *              APR_FNM_NOESCAPE       Disable backslash escaping
00114  *              APR_FNM_PATHNAME       Slash must be matched by slash
00115  *              APR_FNM_PERIOD         Period must be matched by period
00116  *              APR_FNM_CASE_BLIND     Compare characters case-insensitively.
