66 * Try to match the string to the given pattern, return APR_SUCCESS if
67 *    match, else return APR_FNM_NOMATCH.  Note that there is no such thing as
68 *    an illegal pattern.
69 *
70 * With all flags unset, a pattern is interpreted as such:
71 *
72 * PATTERN: Backslash followed by any character, including another
73 *          backslash.<br/>
74 * MATCHES: That character exactly.
75 *
76 * <p>
77 * PATTERN: ?<br/>
78 * MATCHES: Any single character.
79 * </p>
80 *
81 * <p>
82 * PATTERN: *<br/>
83 * MATCHES: Any sequence of zero or more characters. (Note that multiple
84 *          *s in a row are equivalent to one.)
85 *
86 * PATTERN: Any character other than \?*[ or a \ at the end of the pattern<br/>
87 * MATCHES: That character exactly. (Case sensitive.)
88 *
89 * PATTERN: [ followed by a class description followed by ]<br/>
90 * MATCHES: A single character described by the class description.
91 *          (Never matches, if the class description reaches until the
92 *          end of the string without a ].) If the first character of
93 *          the class description is ^ or !, the sense of the description
94 *          is reversed.  The rest of the class description is a list of
95 *          single characters or pairs of characters separated by -. Any
96 *          of those characters can have a backslash in front of them,
97 *          which is ignored; this lets you use the characters ] and -
98 *          in the character class, as well as ^ and ! at the
99 *          beginning.  The pattern matches a single character if it
100 *          is one of the listed characters or falls into one of the
101 *          listed ranges (inclusive, case sensitive).  Ranges with
102 *          the first character larger than the second are legal but
103 *          never match. Edge cases: [] never matches, and [^] and [!]
104 *          always match without consuming a character.
105 *
106 * Note that these patterns attempt to match the entire string, not
107 * just find a substring matching the pattern.
108 *
109 * @param pattern The pattern to match to
110 * @param strings The string we are trying to match
111 * @param flags flags to use in the match.  Bitwise OR of:
112 * <pre>
113 *              APR_FNM_NOESCAPE       Disable backslash escaping
114 *              APR_FNM_PATHNAME       Slash must be matched by slash
115 *              APR_FNM_PERIOD         Period must be matched by period
116 *              APR_FNM_CASE_BLIND     Compare characters case-insensitively.
