    Parameters:
        Process:
            A handle to the process.
            The handle must have the PROCESS_QUERY_INFORMATION or PROCESS_QUERY_LIMITED_INFORMATION access right.
        Flags:
            This parameter can be one of the following values.
            0x00000000     The name should use the Win32 path format.
            0x00000001     The name should use the native system path format.
    Return value:
        If the function succeeds, the return value is a string with the full name of the executable image.
        If the function fails, the return value is zero. To get extended error information, check A_LastError (WIN32).
