Function Documentation

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
