The Buffer Structure

The VdigBufferRec data type defines a buffer structure.



 
typedef struct {

    PixMapHandle        dest;           /* handle to pixel map for

                                            destination buffer */

    Point               location;       /* location of video destination

                                            in pixel map */

    long                reserved;       /* reserved--set to 0 */

} VdigBufferRec;

dest: Contains a handle to the pixel map that defines the destination buffer.
location: Specifies the location of the video destination in the pixel map specified by the dest field. This point identifies the upper-left corner of the destination rectangle. The size and scaling of the destination rectangle are governed by the matrix and mask fields of the buffer list structure that contains this structure.
reserved: Reserved for use by Apple. Set this field to 0.
