JNA CreatePseudoConsole声明

Question

What is correct JNA declaration of CreatePseudoConsole function?

Windows API declaration is following:

HRESULT WINAPI CreatePseudoConsole(
    _In_ COORD size,
    _In_ HANDLE hInput,
    _In_ HANDLE hOutput,
    _In_ DWORD dwFlags,
    _Out_ HPCON* phPC
);

Answer 1

HRESULT is a 32-bit integer , so your function declaration would be int CreatePseudoConsole() .

As for the arguments, you can extend Structure to create your own COORD structure, mapping the two Windows SHORT s to Java's 16-bit integer short .

JNA already has a mapping for WinNT.HANDLE , so just use that. You can optionally use JNA's DWORD mapping, but most of the time I just map those directly to an int .

So the only thing left is the pointer to HPCON , which is not directly mapped. The docs describe this as a pointer to a HANDLE . You can use HANDLEByReference here, or extend that to your own more narrowly typed class. This mapping of HGLRCByReference is a good example to use if you want to create an HPCONByReference.
