Send the contents of the specified buffer to to the client.
Parameters
- hSocket
- An optional parameter that specifies the handle to the client socket.
If this parameter is omitted, the socket handle for the active
client session will be used. If this method is called outside of a
server event handler, the socket handle must be specified.
- lpBuffer
- The pointer to the buffer which contains the data that is to be
sent to the client.
- cbBuffer
- The number of bytes to send from the specified buffer. This
value must be greater than zero.
Return Value
If the method succeeds, the return value is the number of bytes
actually written. If the method fails, the return value is
INET_ERROR. To get extended error information, call the
GetLastError method.
Remarks
The return value may be less than the number of bytes specified by
the cbBuffer parameter. In this case, the data has been
partially written and it is the responsibility of the client
application to send the remaining data at some later point.
