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
