Title: Quick question about return values.
Post by: ctt on November 23, 2005, 09:43:22 AM

I have codesnippets with "return Var" in them... my question, how do i use it? return aint something that masm32 knows by default as far as I know, or is the snippets for some other assembler? ::)

Exampel

Code Select


...
ADDR lpData,ADDR dwSize
invoke RegCloseKey,phkResult
return lpData
...

Thanks!

Most likely it's a macro which does this:

Code Select

mov eax,lpData
ret

(eax is conventionally used for returning values)

It is one of the many macros listed in the MACROS.ASM file provided with the MASM32 package.

Code Select

      return MACRO arg
        mov eax, arg
        ret
      ENDM
