6.3.1 TCP Client Operation
The following figure shows the flow for transferring data with a TCP client.
Note:
- The host application must
register a socket notification callback function. The function must be of
tpfAppSocketCb
type and must handle socket event notifications appropriately. - If the client knows the IP of
the server, it may call
connect
directly as shown in the figure above. If only the server URL is known, then the application must resolve the server URL first calling thegethostbyname
API.
