Function Documentation

int ff_http_do_new_request ( URLContext h,
const char *  uri 
)

Send a new HTTP request, reusing the old connection.

Parameters
hpointer to the ressource
uriuri used to perform the request
Returns
a negative value if an error condition occurred, 0 otherwise

Definition at line 199 of file http.c.

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
destURL context whose authentication state gets updated
srcURL context whose authentication state gets copied
