[x86 asm] PUSH of immediate address

Consider the following output in OllyDbg

Code:

7743A4B8  /$ 68 FA993F77     PUSH ntdll.773F99FA

As I understand it, the program pushes the value found at the address 0x773F99FA onto the stack.

However, does it push a 8-, 16- or 32-bit value?

I guess that simply depends on the processor's word size... like with (all?) other instructions

In your case, since the address is 32-bit sized, your stack might be in 32-bits.
