#include <windows.h>
#include <VdmDbg.h>

BOOL WINAPI ProcessVDMs( DWORD, DWORD, LPARAM );
BOOL WINAPI ProcessTasks( DWORD, WORD, WORD, PSZ, PSZ, LPARAM );

#pragma comment( lib, "vdmdbg.lib" )

void main()
{
// Enumerate VDMs
VDMEnumProcessWOW(
(PROCESSENUMPROC)ProcessVDMs,
(LPARAM)NULL
);

}

BOOL WINAPI ProcessVDMs( DWORD dwProcessId, DWORD dwAttrib,
LPARAM t )
{
printf("VDM Process ID: %d\n", dwProcessId);

// Use process ID of VDM to enumerate through its tasks
VDMEnumTaskWOWEx(
dwProcessId,
(TASKENUMPROCEX)ProcessTasks,
(LPARAM)NULL
);

// Keep enumerating
return FALSE;
}

BOOL WINAPI ProcessTasks( DWORD dwThreadId, WORD hMod16, WORD hTask16,
PSZ pszModName, PSZ pszFileName, LPARAM lParam )
{
// Print task's information
printf("ThreadID: %d\n", dwThreadId);
printf("Module: %d\n", hMod16);
printf("Task: %d\n", hTask16);
printf("ModName: %s\n", pszModName);
printf("File: %s\n", pszFileName);

// Keep enumerating
return FALSE;
}

I think you might be tripping over standard header file stuff; the Windows API for C is not used much differently than other APIs, you include the header file (#include <windows.h>) and then you call functions to interact with the Windows OS.
