The DDCAPBUFFINFO structure contains the capture information.

Syntax

typedef struct _DDCAPBUFFINFO {
  DWORD         dwFieldNumber;
  DWORD         bPolarity;
  LARGE_INTEGER liTimeStamp;
  DWORD         ddRVal;
} DDCAPBUFFINFO, *LPDDCAPBUFFINFO;

Members

dwFieldNumber

Indicates the internal field number of the field captured.

bPolarity

Specifies whether the captured field is an even or odd field. A value of 0x00000001 indicates even, 0x00000000 indicates odd.

liTimeStamp
