Fields

name: *const c_char

url_open: Option<unsafe extern "C" fn(h: *mut URLContext, url: *const c_char, flags: c_int) -> c_int>

url_open2: Option<unsafe extern "C" fn(h: *mut URLContext, url: *const c_char, flags: c_int, options: *mut *mut AVDictionary) -> c_int>

This callback is to be used by protocols which open further nested protocols. options are then to be passed to ffurl_open()/ffurl_connect() for those nested protocols.

url_accept: Option<unsafe extern "C" fn(s: *mut URLContext, c: *mut *mut URLContext) -> c_int>

url_handshake: Option<unsafe extern "C" fn(c: *mut URLContext) -> c_int>

url_read: Option<unsafe extern "C" fn(h: *mut URLContext, buf: *mut c_uchar, size: c_int) -> c_int>

Read data from the protocol. If data is immediately available (even less than size), EOF is reached or an error occurs (including EINTR), return immediately. Otherwise: In non-blocking mode, return AVERROR(EAGAIN) immediately. In blocking mode, wait for data/EOF/error with a short timeout (0.1s), and return AVERROR(EAGAIN) on timeout. Checking interrupt_callback, looping on EINTR and EAGAIN and until enough data has been read is left to the calling function; see retry_transfer_wrapper in avio.c.

url_write: Option<unsafe extern "C" fn(h: *mut URLContext, buf: *const c_uchar, size: c_int) -> c_int>

url_seek: Option<unsafe extern "C" fn(h: *mut URLContext, pos: i64, whence: c_int) -> i64>

url_close: Option<unsafe extern "C" fn(h: *mut URLContext) -> c_int>

url_read_pause: Option<unsafe extern "C" fn(h: *mut URLContext, pause: c_int) -> c_int>

url_read_seek: Option<unsafe extern "C" fn(h: *mut URLContext, stream_index: c_int, timestamp: i64, flags: c_int) -> i64>

url_get_file_handle: Option<unsafe extern "C" fn(h: *mut URLContext) -> c_int>

url_get_multi_file_handle: Option<unsafe extern "C" fn(h: *mut URLContext, handles: *mut *mut c_int, numhandles: *mut c_int) -> c_int>
