Specifically, I want to use Point-to-point Message Queue but because I am still using legacy codes in eVC++ 4 and it only support until PocketPC 2003SE SDK, I cannot find CreateMsgQueue and friends in the headers (the port to newer VisualStudio is still in progess)

I am using the Message Queue to do IPC with apps developed with WM-6.5-DTK (VS2005).

Update:
I am using the following code (taken from msgqueue.h) to store function pointers and load CoreDLL.dll using GetProcAddress() and LoadLibrary() respectively.

HANDLE /*WINAPI*/ (*CreateMsgQueue)(LPCWSTR lpName, LPMSGQUEUEOPTIONS lpOptions);
HANDLE /*WINAPI*/ (*OpenMsgQueue)(HANDLE hSrcProc, HANDLE hMsgQ
                  , LPMSGQUEUEOPTIONS lpOptions);
BOOL /*WINAPI*/ (*ReadMsgQueue)(HANDLE hMsgQ,
     /*__out_bcount(cbBufferSize)*/ LPVOID lpBuffer, DWORD cbBufferSize,
                LPDWORD lpNumberOfBytesRead, DWORD dwTimeout, DWORD *pdwFlags);
BOOL /*WINAPI*/ (*WriteMsgQueue)(HANDLE hMsgQ, LPVOID lpBuffer, DWORD cbDataSize,
                DWORD dwTimeout, DWORD dwFlags);
BOOL /*WINAPI*/ (*GetMsgQueueInfo)(HANDLE hMsgQ, LPMSGQUEUEINFO lpInfo);

BOOL /*WINAPI*/ (*CloseMsgQueue)(HANDLE hMsgQ);

Is the above code alright since I need to comment out WINAPI and __out_bcount(cbBufferSize) in order for them to compile.
