+ *
+ * SYNOPSIS
+ *
+ * SilcBool silc_regex(const char *string, const char *regex,
+ * SilcBuffer match, ...);
+ *
+ * DESCRIPTION
+ *
+ * Matches the `string' to the regular expression `regex'. Returns TRUE
+ * if the `string' matches the regular expression or FALSE if it does not
+ * match. The silc_errno is also set to SILC_ERR_NOT_FOUND.
+ *
+ * The first (whole) match is returned to `match' buffer if it is non-NULL.
+ * The variable argument list are buffers where multiple matches are
+ * returned in case of group (parenthesized) regular expression. The caller
+ * needs to know how many pointers to provide, in order to get all matches.
+ * If `match' is non-NULL the variable argument list must be ended with
+ * NULL. The data in the `match' and in any other buffer is from `string'
+ * and must not be freed by the caller.
+ *
+ * EXAMPLE
+ *
+ * // Simple match
+ * if (!silc_regex("foobar", "foo.", NULL))
+ * no_match;
+ *
+ * // Get the pointer to the first match
+ * if (!silc_regex("foobar", ".bar", &match, NULL))
+ * no_match;
+ *
+ * // Group match
+ * SilcBufferStruct match, sub1, sub2;
+ *
+ * if (!silc_regex("Hello World", "(H..).(o..)", &match, &sub1, &sub2, NULL))
+ * no_match;
