assembly - 连接寄存器中的字符串并打印它们

Question

我正在尝试调用 cpuid 并将 EBX、ECX 和 EDX 的输出打印到控制台，但它打印的是空行

这是我的代码：

.586 

.model flat,stdcall 

option casemap:none 

include \masm32\include\windows.inc 
include \masm32\include\kernel32.inc
includelib \masm32\lib\kernel32.lib  

.data
.data?
mybuffer byte 100 dup(?)

.code 
start: 

mov      eax, 0
cpuid

invoke   lstrcpy, addr mybuffer, ebx   
invoke   lstrcat, addr mybuffer, ecx
invoke   lstrcat, addr mybuffer, edx

invoke   GetStdHandle, STD_OUTPUT_HANDLE
invoke   WriteConsole, eax, addr mybuffer, sizeof mybuffer, NULL, NULL

invoke   ExitProcess, 0

end start
