Returned Value
DEF_OK,
Socket transmit queue size successfully configured;
DEF_FAIL,
otherwise.
Required Configuration
None.
Notes / Warnings
For datagram sockets, configured size does not:
- Partially truncate any transmitted data but instead allows data from exactly one transmitted packet buffer to overflow the configured size since each datagram must be transmitted atomically (see section C-13-48 “NetSock_TxData() / send() (TCP) NetSock_TxDataTo() / sendto() (UDP)”).
For steam sockets, size may be required to be configured prior to connecting (see section C-14-6 “NetTCP_ConnCfgTxWinSize()”).
