vlc_getaddrinfo()

int vlc_getaddrinfo	(	const char *	node,
		unsigned	port,
		const struct addrinfo *	hints,
		struct addrinfo **	res
	)

Resolves a host name to a list of socket addresses (like getaddrinfo()).

Parameters

node	host name to resolve (encoded as UTF-8), or NULL
i_port	port number for the socket addresses
p_hints	parameters (see getaddrinfo() manual page)
res	pointer set to the resulting chained list.

Returns

0 on success, a getaddrinfo() error otherwise. On failure, *res is undefined. On success, it must be freed with freeaddrinfo().

vlc_getProxyUrl()

char * vlc_getProxyUrl

(

const char *

url

)

Determines the network proxy server to use (if any).

This function fetch the Android proxy using the System.getProperty() method with "http.proxyHost" and "http.proxyPort" keys. This is working only for Android 4.0 and after.

Parameters

url	absolute URL for which to get the proxy server (unused)

Returns

proxy URL, NULL if no proxy or error

Parameters

url	absolute URL for which to get the proxy server

Returns

proxy URL, NULL if no proxy or error
