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 function NetSock_TxData()).

For steam sockets, size may be required to be configured prior to connecting (see function NetTCP_ConnCfgTxWinSize()).
