+ * Determines whether a path matches a wildcard pattern.
+ *
+ * @path
+ * The path to match. Assumptions: All path separators must be @path_sep,
+ * there cannot be consecutive path separators, there cannot be a trailing
+ * path separator, and there must be exactly one leading path separator.
+ *
+ * @path_nchars
+ * Number of characters in @path.
+ *
+ * @wildcard
+ * The wildcard pattern to match. It can contain the wildcard characters
+ * '*' and '?'. The former matches zero or more characters except
+ * @path_sep, and the latter matches any character except @path_sep. All
+ * path separators in the pattern must be @path_sep, and there cannot be
+ * consecutive path separators, and there cannot be a trailing path
+ * separator. If there is a leading path separator, the match is attempted
+ * with the filename only; otherwise, the match is attempted with the whole
+ * path.
+ *
+ * @path_sep
+ * Path separator character used in @path and @wildcard.
+ *
+ * @prefix_ok
+ * If %true, allow a prefix of @path, terminated by a path separator, to
+ * match the pattern, in addition to @path itself. In other words, return
+ * %true if the pattern actually matches one of the ancestor directories of
+ * @path.
+ *
+ * Returns %true if there was a match; %false if there was not.
