RasGetBuffer (Compact 2013)
3/26/2014
This function allocates memory for sending or receiving data over the port connected to the server. A custom-scripting DLL, which is implemented by the developer, calls RasGetBuffer through a function pointer. RAS passes the function pointer through the phnRasGetBuffer parameter of the DLL's RasCustomScriptExecute function.
