NAME

       wslay_event_recv - Receive messages

SYNOPSIS

       #include <wslay/wslay.h>

       int wslay_event_recv(wslay_event_context_ptr ctx)

DESCRIPTION

       wslay_event_recv()    receives    messages    from    peer.     When    receiving   messages,   it   uses
       wslay_event_recv_callback function. Single  call  of  this  function  receives  multiple  messages  until
       wslay_event_recv_callback function sets error code WSLAY_ERR_WOULDBLOCK.

       wslay_event_recv()    calls    following    callback    functions    for    their    own    event    (See
       wslay_event_context_server_init()  or  wslay_event_context_client_init()  for   the   details   of   each
       callbacks).

       wslay_event_on_frame_recv_start_callback
              Called when a new frame starts to be received.

       wslay_event_on_frame_recv_start_callback
              Called when a new frame starts to be received.

       wslay_event_on_frame_recv_chunk_callback
              Called when a chunk of frame payload is received.

       wslay_event_on_frame_recv_end_callback
              Called when a frame is completely received.

       wslay_event_on_msg_recv_callback
              Called when a message is completely received.

       When  close control frame is received, this function automatically queues close control frame.  Also this
       function calls wslay_event_set_read_enabled() with second argument 0 to disable further read from peer.

       When ping control frame is received, this function automatically queues pong control frame.

       In  case  of  a  fatal   error   which   leads   to   negative   return   code,   this   function   calls
       wslay_event_set_read_enabled() with second argument 0 to disable further read from peer.

RETURN VALUE

       wslay_event_recv() returns 0 if it succeeds, or one of the following negative error codes:

       WSLAY_ERR_CALLBACK_FAILURE
              User defined callback function is failed.

       WSLAY_ERR_NOMEM
              Out of memory.

       When  negative  error  code is returned, application must not make any further call of wslay_event_recv()
       and must close WebSocket connection.
