PDD_FillBuffer is called by the MDD to transfer or DMA data to the buffer.

Syntax

DWORD PDD_FillBuffer( 
LPVOID PDDContext, 
ULONG ulModeType, 
PUCHAR pImage 
);

Parameters

  • LPVOID PDDContext
    [in]

    This is the return value of PDD_Init.

  • ULONG ulModeType
    T[in]

    There are three modes supported, i.e., CAPTURE, PREVIEW and STILL

  • PUCHAR pImage
    [in]

    Pointer to the buffer that needs to be filled by the PDD

Return Value

PDD specific. ERROR_SUCCESS represents success. Any other value will be treated as error.

Remarks

When the PDD layer receives an interrupt for sensor data availability, it calls the MDD_HandleIO method implemented by the MDD layer. MDD_HandleIO is used internally to call PDD_FillBuffer to let the PDD layer transfer or DMA data to the buffer.
