The DIPERIODIC structure contains type-specific information for effects that are marked as DIEFT_PERIODIC.
The structure describes a periodic effect.
A pointer to a single DIPERIODIC structure for an effect is passed in the lpvTypeSpecificParams member of the DIEFFECT structure.
typedef struct DIPERIODIC { DWORD dwMagnitude; LONG lOffset; DWORD dwPhase; DWORD dwPeriod; } DIPERIODIC, *LPDIPERIODIC; typedef const DIPERIODIC *LPCDIPERIODIC;
A device driver cannot provide support for all values in the dwPhase member. In this case, the value is rounded off to the nearest supported value.
Windows NT/2000: Requires Windows 2000.
Windows 95/98: Requires Windows 95 or later. Available as a redistributable for Windows 95.
