I used to do this in VC++6, but now I'm kinda stuck:

[class member]
        HANDLE Handles[2];
[in member function]
        WaitForMultipleObjects(2, Handles, FALSE, INFINITE);

This doesn't work in a managed class: apparently an array name, even
with an explicit __nogc in the array declaration, is no longer the
same as a pointer to its first element?

        HANDLE Handles __nogc [2];
        WaitForMultipleObjects(2, Handles, FALSE, INFINITE);

error C2664: 'WaitForMultipleObjects' : cannot convert parameter 2
from 'HANDLE [2]' to 'const HANDLE * '

And when I write

        WaitForMultipleObjects(2, &Handles[0], FALSE, INFINITE);

the compiler tells me that &Handles[0] is a __gc pointer, despite the
__nogc in the array declaration ???

Do I really have to resort to allocating memory for the array myself,
like this?

        HANDLE __nogc *Handles;
        Handles = (HANDLE __nogc *)malloc(2 * sizeof(HANDLE));
        Handles[0] = ...
        Handles[1] = ...
        WaitForMultipleObjects(...);
        free(Handles);

Or won't this work either?

Lucvdv,

No. You only have to pin the object the array is declared in first:

WhateverClass __pin* pinnedThis = this;
WaitForMultipleObjects(2, pinnedThis->Handles, FALSE, INFINITE);

Or something like that.
