Title: Prototype - a little slim on details
Post by: Magnum on August 17, 2013, 08:42:03 AM

I don't see the tag for code that is usually shown.

Hutch's description is more detailed, but I am the person who needs to see examples.

Microsoft has none.

Proto

language type - there are tons of language, so what are the available ones and when would you use them ?

I recall that C can use inline assembly.

I see that you separate parameters with commas.

PROTO

Syntax: label PROTO [distance] [langtype] [, [parameter]:tag]...

Description

Defines a prototype for a subsequent procedure. Informs the assembler about how many and what kind of arguments should be expected in a procedure definition. This allows the assembler to perform type checking on arguments.

If you define a prototype for all stack-based procedures defined with the PROC directive, you can place procedure prototypes in a separate include file. This is recommended when using procedures in a library file

This is one example of something I need a prototype for.

Custom proc
     PUSH EBP
     MOV EBP,ESP
     PUSH ECX
     PUSH EAX
     PUSH ECX
     MOV EAX,DWORD PTR FS:[18]
     MOV EAX,DWORD PTR DS:[EAX+30]
     MOV ECX,DWORD PTR DS:[EAX]
     MOV DWORD PTR SS:[EBP-4],ECX
     POP ECX
     POP EAX
     MOV EAX,DWORD PTR SS:[EBP-4]
     SHR EAX,10
     AND EAX,1
     MOV ESP,EBP
     POP EBP
     RET
   Custom endp
