如何使用ShellExecuteEx传递参数？

I am using IPC for shared memory.

我正在使用IPC来共享内存。

I need to turn on another program with IPC, but I want to know how to pass arguments.

我需要用IPC打开另一个程序，但我想知道如何传递参数。

Below is a execute function for my IPC class.

下面是我的IPC类的执行函数。

int execute(std::string exePath, std::string exeName, int console = 1)
{
    SHELLEXECUTEINFOA p_info;

    ZeroMemory(&p_info, sizeof(SHELLEXECUTEINFOA)); //초기화
    p_info.cbSize = sizeof(SHELLEXECUTEINFOA);
    p_info.lpFile = exeName.c_str(); // 파일 이름
    p_info.lpDirectory = exePath.c_str(); //파일 위치

    p_info.nShow = console; //콘솔 show
    p_info.fMask = SEE_MASK_NOCLOSEPROCESS;

    return ShellExecuteEx(&p_info);
};

Arguments are passed using the lpParameters member of SHELLEXECUTEINFO.

使用SHELLEXECUTEINFO的lpParameters成员传递参数。

其他一些评论：

Since you are explicitly using the ANSI version of the struct, SHELLEXECUTEINFOA, it would be appropriate to do the same for the function call and use ShellExecuteExA.
由于您明确使用结构的ANSI版本SHELLEXECUTEINFOA，因此对函数调用执行相同操作并使用ShellExecuteExA是合适的。
Avoid the call to ZeroMemory by initialising the struct as part of the declaration: SHELLEXECUTEINFOA p_info = { 0 };
通过初始化结构作为声明的一部分来避免调用ZeroMemory：SHELLEXECUTEINFOA p_info = {0};
You use SEE_MASK_NOCLOSEPROCESS but then fail to close the process handle. This is a handle leak.
您使用SEE_MASK_NOCLOSEPROCESS但无法关闭进程句柄。这是一个手柄泄漏。
Unless you use ShellExecuteEx with the runas verb to elevate the process, it would seem more appropriate to call CreateProcess. Why ask ShellExecuteEx to call CreateProcess when you can do so directly?
除非您使用带有runas谓词的ShellExecuteEx来提升进程，否则调用CreateProcess似乎更合适。为什么要在可以直接执行此操作时请求ShellExecuteEx调用CreateProcess？
