Using this Function
The function should be called in your main, WinMain, or DllMain function. Which of these
three functions you are using determines the parameter values you should pass to InitCVIRTE.
The following examples show how to use InitCVIRTE in each case.
int main (int argc, char *argv[])
{
if (InitCVIRTE (0, argv, 0) == 0)
return -1; /* out of memory */
/* your other code */
return 0;
}
int __stdcall WinMain (HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPSTR lpszCmdLine,
int nCmdShow)
{
if (InitCVIRTE (hInstance, 0, 0) == 0)
return -1; /* out of memory */
/* your other code */
return 0;
}
int __stdcall DllMain (void *hinstDLL, int fdwReason,
void *lpvReserved)
{
if (fdwReason == DLL_PROCESS_ATTACH)
{
if (InitCVIRTE (hinstDLL, 0, 0) == 0)
return 0; /* out of memory */
/* your other ATTACH code */
}
else if (fdwReason == DLL_PROCESS_DETACH)
{
