-/****f* silcutil/SilcStrUtilAPI/silc_mime_parse
- *
- * SYNOPSIS
- *
- * bool
- * silc_mime_parse(const unsigned char *mime, SilcUInt32 mime_len,
- * char *version, SilcUInt32 version_size,
- * char *content_type, SilcUInt32 content_type_size,
- * char *transfer_encoding,
- * SilcUInt32 transfer_encoding_size,
- * unsigned char **mime_data_ptr,
- * SilcUInt32 *mime_data_len);
- *
- * DESCRIPTION
- *
- * Parses MIME header indicated by `mime' data block of length of
- * `mime_len'. Returns TRUE if the `mime' is valid MIME object.
- * Parses from the MIME header the MIME Version (if present) and
- * copies it to the `version' pointer if provided, content type
- * indicating the data in the MIME object and copies it to the
- * `content_type' if provided, and the tranfer encoding (if present)
- * indicating the encoding of the data and copies it to the
- * `content_transfer_encoding' if provided.
- *
- * The pointer to the actual data in the MIME object is saved into
- * `mime_data_ptr'. The pointer is a location in the `mime' and it
- * does not allocate or copy anything, ie. the `mime_data_ptr' is a
- * pointer to the `mime'. The `mime_data_len' indicates the length of
- * the data without the MIME header. The caller is responsible of
- * NULL terminating the buffers it provides.

- *
- * DESCRIPTION
- *
- * Checks that the 'identifier' string is valid identifier string
- * and does not contain any unassigned or prohibited character. This
- * function is used to check for valid nicknames, server names,
- * usernames, hostnames, service names, algorithm names, other security
- * property names, and SILC Public Key name.
- *
- * If the 'max_allowed_length' is non-zero the identifier cannot be
- * longer than that, and NULL is returned if it is. If zero (0), no
- * length limit exist. For nicknames the max length must be 128 bytes.
- * Other identifiers has no default limit, but application may choose
-* one anyway.
- *
- * Returns the validated string, that the caller must free. Returns
- * NULL if the identifier string is not valid or contain unassigned or
- * prohibited characters. Such identifier strings must not be used
- * SILC protocol. The returned string is always in UTF-8 encoding.
- * The length of the returned string is in 'out_len'.
- *
- * NOTES
- *
- * In addition of validating the identifier string, this function
- * may map characters to other characters or remove characters from the
- * original string. This is done as defined in the SILC protocol. Error
- * is returned only if the string contains unassigned or prohibited
- * characters. The original 'identifier' is not modified at any point.
