Prototype

          CPU_BOOLEAN NetSock_CfgTxQ_Size(NET_SOCK_ID         sock_id,
                                          NET_SOCK_DATA_SIZE  size
                                          NET_ERR            *p_err);

Arguments

sock_id

This is the socket ID of socket to configure transmit queue size.

size

Desired transmit queue size.

p_err

Pointer to variable that will receive the return error code from this function:

NET_SOCK_ERR_NONE
NET_SOCK_ERR_INVALID_TYPE
NET_SOCK_ERR_INVALID_PROTOCOL
NET_SOCK_ERR_INVALID_DATA_SIZE
NET_INIT_ERR_NOT_COMPLETED
NET_SOCK_ERR_INVALID_SOCK
NET_SOCK_ERR_NOT_USED
NET_TCP_ERR_INVALID_CONN
NET_TCP_ERR_INVALID_ARG
NET_TCP_ERR_CONN_NOT_USED
NET_CONN_ERR_INVALID_CONN
NET_CONN_ERR_NOT_USED
NET_ERR_FAULT_LOCK_ACQUIRE

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).
