是否有WinAPI可以从命令行获取带有可选空格和其他参数的文件名？

Question

My goal is get a file name from a command line call/string. For instance, if I have the following strings on the input:

C:\WINDOWS\system32\mstsc.exe /v:%WKSNAME% /f
"C:\Users\User Name\Desktop\My Program.exe" /?

The API should return the following respectively:

mstsc.exe
My Program.exe

So I tried to use splitpath function, and although it works for a very simple file path, it totally fails on my two examples above.

I understand that I can write my own parser (so please don't offer that.) I'm curious if there's a built-in Windows API that does it already?

PS. There must be one that OS uses internally to parse those.

PS2. Here's the code I've been toying with:

TCHAR buffFileName[MAX_PATH];
TCHAR buffExt[MAX_PATH];

LPCTSTR strInputPath = L"C:\\WINDOWS\\system32\\mstsc.exe /v:%WKSNAME% /f";
if(_tsplitpath_s(strInputPath, NULL, 0, NULL, 0, buffFileName, MAX_PATH, buffExt, MAX_PATH) == 0)
{
    //Got something
}

I believe PathFindFileName may be what you're looking for. From the docs:

Searches a path for a file name.

The examples within the docs seem to show the exact behavior you describe.

If you'd rather parse the entire command-line, CommandLineToArgvW may be helpful. It takes a command-line and splits it into an array containing the filename and any arguments.

This function's parsing rules are fairly intricate, so be sure to look over the docs, but a simple explanation of them can be found in this answer .
