must be
a handle passed by the
connect_proc
callback function.

OCX_ERR_BADPARAM connHandle or offset/dataSize is invalid
Example
OCXHANDLE apihandle;
OCXHANDLE connHandle;
BYTE buffer[128];

OCXcip_WriterConnected (apiHandle, connHandle, buffer, 0, 128);
OCXcip_ImmediateOutput (apiHandle, connHandle);
