title is obscure, my purpose is: i want my usermode application can read a unknown sized data like registry value's data, and i try this method:
1. KeStackAttachProcess/KeUnstackDetachProcess to attach to my process.
2. call ZwAllocateVirtualMemory to allocating memory, then copy data to returned memory pointer.
3. send to process at least 2 informations: size of data and pointer to that data, so process can read correctly.
4. free all after read.
i tried this method and usermode process can read that data correctly.
my question is: is this a good approach to solve my problem? any other good methods?
P/S: mods please move this topic to NTDEV, thanks.
