使用 MASM 编译器将结构嵌套到程序集文件中

Question

有人知道如何使用Windows编译器ml在程序集中创建嵌套结构吗.exe

我想声明startupinfoexa的结构(https://learn.microsoft.com/en-us/windows/win32/api/winbase/ns-winbase-startupinfoexa(，但它包含结构startupinfoa(https://learn.microsoft.com/en-us/windows/win32/api/processthreadsapi/ns-processthreadsapi-startupinfoa(

startupinfoa 结构在我的代码中声明如下：

STARTUPINFOA    struct 
cb            DWORD    ?
lpReserved    DWORD    ?
lpDesktop     DWORD    ?
lpTitle       DWORD    ?
dwX           DWORD    ?
dwY           DWORD    ?
dwXSize       DWORD    ?
dwYSize       DWORD    ?
dwXCountChars    DWORD    ?
dwYCountChars    DWORD    ?
dwFillAttribute  DWORD    ?
dwFlags       DWORD    ?
wShowWindow   WORD    ?
cbReserved2   WORD    ?
lpReserved2   DWORD    ?
hStdInput     DWORD    ?
hStdOutput    DWORD    ?
hStdError     DWORD    ?
STARTUPINFOA    ends

它运行良好，但现在我想在我的代码中使用 startupinfoexa，但我真的不知道如何声明它，因为它包含 startupinfoa 结构。我在下面使用的内容不起作用：

STARTUPINFOEXA struct
StartupInfo     STARTUPINFOA ?
lpAttributeList DWORD ?
STARTUPINFOEXA ends

知道吗？

谢谢

用尖括号做：

STARTUPINFOEXA struct
StartupInfo     STARTUPINFOA <>
lpAttributeList DWORD ?
STARTUPINFOEXA ends

示例(程序在控制台中执行"cmd /cDIR"(：
