stdcall and cdecl stack alignment size

Question

I have two questions:

Is the stack alignment for the stdcall calling convention always 4 bytes, or is it 4 for a 32 bit machine and 8 for a 64 bit machine?
What is the stack alignment size for cdecl?

I am using Microsoft Visual Studio 2010.

I would like to add: Is there a way to get the alignment size? e.g. does sizeof(int) always work? — panzi, Jun 18 '11 at 18:20

Stack alignment for stdcall is always 4 bytes.

The stack alignment for cdecl is usually the size of the argument, but may be affected by compiler settings.
