vlc_h2_frame_send()

static int vlc_h2_frame_send ( struct vlc_tls *  tls, struct vlc_h2_frame *  f  )

static

Sends one HTTP/2 frame through TLS.

This function sends a whole HTTP/2 frame through a TLS session, then releases the memory used by the frame.

The caller must "own" the write side of the TLS session.

Note

This is a blocking function and may be a thread cancellation point.

Returns

0 on success, -1 if the connection failed

vlc_h2_output_dequeue()

static struct vlc_h2_frame* vlc_h2_output_dequeue ( struct vlc_h2_output *  out )

static

Dequeues one outgoing HTTP/2.

vlc_h2_output_thread()

static void* vlc_h2_output_thread ( void *  data )

vlc_https_send()

static ssize_t vlc_https_send ( vlc_tls_t *  tls, const void *  buf, size_t  len  )

static

Sends bytes to a connection.

Note

This may be a cancellation point. The caller is responsible for serializing writes on a given connection.
