    Blit

    Description:

    During bit blit, color space conversion (CSC), scaling, and rotation can be implemented.

    Parameters:

    Name

    Description
    srcSurface Indicates the pointer to the source bitmap.
    srcRect Indicates the pointer to the rectangle of the source bitmap.
    dstSurface Indicates the pointer to the destination bitmap.
    dstRect Indicates the pointer to the rectangle of the destination bitmap.

    Returns:

    Returns 0 if the operation is successful; returns an error code defined in otherwise.

    Description:

    Synchronizes hardware acceleration.

    Use this function for hardware acceleration synchronization when hardware acceleration is used to draw and blit bitmaps. This function blocks the process until hardware acceleration is complete.

    Parameters:

    Returns:
