What are <Bad Ptr> in visual C++?

Afetr i execute following statement:------------>

char * result = (char*) VirtualAlloc(NULL, 10,
MEM_RESERVE | MEM_TOP_DOWN,
PAGE_EXECUTE_READWRITE);


When i check the value of result it says:<Bad Ptr> and shows some address.
What does it mean?

That non-zero value in the pointer is put there by Visual C++ to indicate the pointer has never been initialized.

You need to call GetLastError after VirtualAlloc to see if your allocation worked.
