Syntax

BOOL KernelLibIoControl(
    HANDLE hDevice,           // handle to the DLL
    DWORD dwIoControlCode,    // use IOCTL_KLIB_MAKESNAP
    LPVOID lpInBuffer,        // pointer to input buffer
    DWORD nInBufferSize,      // input buffer size
    LPVOID lpOutBuffer,       // pointer to output buffer
    DWORD nOutBufferSize,     // output buffer size
    LPDWORD lpBytesReturned   // number of bytes returned
);

Parameters

  • hDevice
