Arguments
conn_id_tcp
TCP connection handle ID to configure transmit immediate acknowledgement for received and pushed TCP segments.
tx_immed_ack_en
Desired value for TCP connection transmit immediate acknowledgement for received and pushed TCP segments:
DEF_ENABLED
TCP connection acknowledgements immediately transmitted for any pushed TCP segments received.
DEF_DISABLED
TCP connection acknowledgements not immediately transmitted for any pushed TCP segments received.
perr
Pointer to variable that will receive the return error code from this function:
NET_TCP_ERR_NONE
NET_TCP_ERR_INVALID_ARG
NET_TCP_ERR_INVALID_CONN
NET_TCP_ERR_CONN_NOT_USED
NET_ERR_INIT_INCOMPLETE
NET_OS_ERR_LOCK
Returned Value
DEF_OK,
TCP connection’s transmit immediate acknowledgement for received and pushed TCP segments successfully configured, if no errors.
DEF_FAIL,
otherwise.
Required Configuration
Available only if TCP is enabled (see TCP Layer Configuration).
Notes / Warnings
The conn_id_tcp argument represents the TCP connection handle – not the socket handle. The following code may be used to get the TCP connection handle and configure TCP connection parameters (see also NetSock_GetConnTransportID):
NetTCP_ConnCfgTxAckImmedRxdPushEn() is called by application function(s) and must not be called with the global network lock already acquired. It must block all other network protocol tasks by pending on and acquiring the global network lock (see “net.h Note #3”). This is required since an application's network protocol suite API function access is asynchronous to other network protocol tasks.
