@PACKAGE_VERSION@                                 Apr 22, 2024                               WSLAY_EVENT_SEND(3)

wslay_event_send()    sends   queued   messages   to   peer.    When   sending   a   message,   it   uses
       wslay_event_send_callback function.  Single call of  wslay_event_send()  sends  multiple  messages  until
       wslay_event_send_callback sets error code WSLAY_ERR_WOULDBLOCK.

       If  ctx  is initialized for WebSocket client use, wslay_event_send() uses wslay_event_genmask_callback to
       get new mask key.

       When a message  queued  using  wslay_event_queue_fragmented_msg()  is  sent,  wslay_event_send()  invokes
       wslay_event_fragmented_msg_callback for that message.

       After  close  control  frame  is  sent,  this  function calls wslay_event_set_write_enabled() with second
       argument 0 to disable further transmission to peer.

       If there are any pending messages, wslay_event_want_write() returns 1, otherwise returns 0.

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

wslay_event_send() 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_send()
       and must close WebSocket connection.
