#define xmmsv_check_type

((type) > XMMSV_TYPE_NONE && (type) < XMMSV_TYPE_END)

Function Documentation

xmmsv_t* xmmsv_decode_url

(

const xmmsv_t *

inv

)

Decode an URL-encoded string.

Some strings (currently only the url of media) has no known encoding, and must be encoded in an UTF-8 clean way. This is done similar to the url encoding web browsers do. This functions decodes a string encoded in that way. OBSERVE that the decoded string HAS NO KNOWN ENCODING and you cannot display it on screen in a 100% guaranteed correct way (a good heuristic is to try to validate the decoded string as UTF-8, and if it validates assume that it is an UTF-8 encoded string, and otherwise fall back to some other encoding).

Do not use this function if you don't understand the implications. The best thing is not to try to display the url at all.

Note that the fact that the string has NO KNOWN ENCODING and CAN NOT BE DISPLAYED does not stop you from open the file if it is a local file (if it starts with "file://").

Parameters

url	the xmmsv_t containing a url-encoded string

Returns

a new xmmsv_t containing the decoded string as a XMMSV_BIN or NULL on failure

xmmsv_t *

v

)

int xmmsv_dict_format	(	char *	target,
		int	len,
		const char *	fmt,
		xmmsv_t *	val
	)

This function will make a pretty string about the information in xmmsv dict.

Parameters

target	A allocated char *
len	Length of target
fmt	A format string to use. You can insert items from the dict by using specialformat "${field}".
val	The xmmsv_t that contains the dict.

Returns

The number of chars written to target

char* xmmsv_encode_url

(

const char *

url

)

Encodes an url.

The encoded url is allocated using malloc and has to be freed by the user.

Parameters

url	The url to encode.

Returns

The encoded url

char* xmmsv_encode_url_full	(	const char *	url,
		xmmsv_t *	args
	)

Encodes an url with arguments stored in dict args.

The encoded url is allocated using malloc and has to be freed by the user.

Parameters

url	The url to encode.
args	The dict with arguments, or NULL.

Returns

The encoded url

xmmsv_t* xmmsv_propdict_to_dict	(	xmmsv_t *	propdict,
		const char **	src_prefs
	)

Helper function to transform a key-source-value dict-of-dict xmmsv_t (formerly a propdict) to a regular key-value dict, given a list of source preference.

Parameters

propdict	A key-source-value dict-of-dict xmmsv_t.
src_prefs	A list of source names or patterns. Must be NULL-terminated. If this argument is NULL, the default source preferences is used.

Returns

An xmmsv_t containing a simple key-value dict. Must be unreffed manually when done.

int xmmsv_utf8_validate

)

Check if a string is valid UTF-8.
