Function Documentation

int ff_http_do_new_request	(	URLContext *	h,
		const char *	uri
	)

Send a new HTTP request, reusing the old connection.

Parameters:

	h	pointer to the resource
	uri	uri used to perform the request

Returns:: a negative value if an error condition occurred, 0 otherwise

void ff_http_init_auth_state	(	URLContext *	dest,
		const URLContext *	src
	)

Initialize the authentication state based on another HTTP URLContext.

This can be used to pre-initialize the authentication parameters if they are known beforehand, to avoid having to do an initial failing request just to get the parameters.

Parameters:

	dest	URL context whose authentication state gets updated
	src	URL context whose authentication state gets copied
