Allocating memory at a specific location

[redbull]

Hi Guys,

Here is a question and I figure it might be possible to implement cause the windows LOADER seems to do this. (maybe i am just a fool )

I have a code generator which generates a code packet in memory. I want to take that code packet and a corresponding data packet and send it to clients, get them to perform the operations and send the results back (yes its a distributed processing application).

However the problem is I want to carry the data seperate to the code packet so I need to be able to allocate a data block in memory at a specific location (hard coded into the code packet). As opposed to carrying the code and data together and using "virus like" techniques to find out where I am in memroy (eg a call <addr> and a pop ebp pair).

I guess (from what I know about the PE header format) the windows loader uses this technique to put the required EXE code in the correct memory location.

How is this done?

Thanks for your help
