How can I do this? I have 64bit cpu and I need last 4 bytes of this offset to an unsigned long, I tried casting etc but i always get loss of precision in last 2 bytes
what can i do? thanks pd. my application MUST be x86

thanks

If you're compiling for x86 then the void* is already 32-bits.

^^
There's that... but if compiling for 64-bit (assuming little endian):

__int32 foo = * (__int32 *) &x64;

You're right disawowed, however, i don't know why im getting loss of precision in the void* to long casting :S

Just use ULONG_PTR instead of long.

Hope that helps

Thaks for reply, but i still getting the same result:

2577

See how z =/= loadDll_end and zvoid =/=loadDll_end

Also I've to say that loadDll_end is __declspec(naked) void loadDll_end() { }

+ im in debug mode

Would you be so kind as to tell us the error/warning number?

Additionally try your example with the "PtrToUlong" macro.

Something like:

You're not losing precision. One of those two addresses is a jmp to the other one (check the disassembly if you don't believe me). Change to release mode and you won't have that problem.
