So I have been playing around with RPC stuff lately, and I had a quick question. Taking a definition of:



long   sub_40F7D0 (

 [in] handle_t  arg_1,

 [in] struct struct_1 * arg_2,

 [in] long  arg_3,

 [in][string] char * arg_4

);

Is the 'struct' parameter one that is sent on the wire?

well, I don't know much about RPC and can't determine where your code comes from. there is a possible to return a value via pass-by-reference arguments, so, you have to analyze code in IDA or set breakpoint on the argument to see: if it's changed or not.

> Is the \'struct\' parameter one that is sent on the wire? Yes, the struct will be sent over the wire along with the long and string after it. However, the handle_t will not. "Parameters of type handle_t (primitive handle parameters) are not transmitted on the network." http://msdn2.microsoft.com/en-us/library/aa366849.aspx We are in the process of automating all of this idl bs and will put up the code and a handy reference soon.
