NAME
wslay_event_queue_msg - Queue a message for future transmission
SYNOPSIS
#include <wslay/wslay.h> int wslay_event_queue_msg(wslay_event_context_ptr ctx, const struct wslay_event_msg *arg) int wslay_event_queue_msg_ex(wslay_event_context_ptr ctx, const struct wslay_event_msg *arg, uint8_t rsv)
DESCRIPTION
wslay_event_queue_msg() and wslay_event_queue_msg_ex() queue message specified in arg. The struct wslay_event_msg is defined as: struct wslay_event_msg { uint8_t opcode; const uint8_t *msg; size_t msg_length; }; The opcode member is opcode of the message. The msg member is the pointer to the message data. The msg_length member is the length of message data. This function supports both control and non-control messages and the given message is sent without fragmentation. If fragmentation is needed, use wslay_event_queue_fragmented_msg() function instead. This function makes a copy of msg of length msg_length. This function just queues a message and does not send it. wslay_event_send() function call sends these queued messages. wslay_event_queue_msg_ex() additionally accepts rsv parameter, which is a reserved bits to send. To set reserved bits, use macro WSLAY_RSV1_BIT, WSLAY_RSV2_BIT, and WSLAY_RSV3_BIT. See wslay_event_config_set_allowed_rsv_bits() to see the allowed reserved bits to set.
RETURN VALUE
wslay_event_queue_msg() and wslay_event_queue_msg_ex() return 0 if it succeeds, or returns the following negative error codes: WSLAY_ERR_NO_MORE_MSG Could not queue given message. The one of possible reason is that close control frame has been queued/sent and no further queueing message is not allowed. WSLAY_ERR_INVALID_ARGUMENT The given message is invalid; or RSV1 is set for control frame; or bit is set in rsv which is not allowed (see wslay_event_config_set_allowed_rsv_bits()). WSLAY_ERR_NOMEM Out of memory.
