此示例演示如何直接转到WindowsAPI，而不是在C标准库中链接。 global _main extern _GetStdHandle@4
extern _WriteFile@20
extern _ExitProcess@4
section .text
_main:
; DWORD bytes;
mov ebp, esp sub esp, 4
; hStdOut = GetstdHandle( STD_OUTPUT_HANDLE)
push -11
call _GetStdHandle@4
mov ebx, eax
; WriteFile( hstdOut, message, length(message), &bytes, 0);
push 0
lea eax, [ebp-4]
push eax
push (message_end - message)
push message
push ebx
call _WriteFile@20
; ExitProcess(0)
push 0
call _ExitProcess@4
; never here

这些是使用WindowsAPI调用的Win 32和Win 64示例。他们是为MASM而不是NASM，但看看他们。您可以在这，这个文章。;---ASM Hello World Win32 MessageBox.386.model flat, stdcall

/defaultlib:kernel32.lib /defaultlib:user32.lib /entry:Main或者对于64位可执行文件：ml64.exe [filename] /link /subsystem:windows
/defaultlib:kernel32.lib /defaultlib:user32.lib /entry:main
