REGFILTER2

  • 项目

This structure describes a filter for registration through the IFilterMapper2 interface.

typedef struct
{
  DWORD dwVersion;
  DWORD dwMerit;

  /* unnamed union */
  [switch_is(dwVersion)] [switch_type(DWORD)] union
  {
  [case(1)]

  struct
  {
  ULONG cPins;
  [size_is(cPins)] const REGFILTERPINS *rgPins;
  };

  [case(2)]

  struct
  {
  ULONG cPins2;
  [size_is(cPins2)] const REGFILTERPINS2 *rgPins2;
  };
  [default]
  ;
  } ;
} REGFILTER2;

Members

  • dwVersion
    Indicates the filter registration format to use.
  • dwMerit
    Position in the order of enumeration. Filters or categories with higher merit are enumerated first.
  • cPins
    Number of pins (if dwVersion = 1).
  • rgPins
    Array of REGFILTERPINS representing each pin to be registered (if dwVersion = 1).
  • cPins2
    Number of pins (if dwVersion = 2).
  • rgPins2
    Array of REGFILTERPINS2 representing each pin to be registered (if dwVersion = 2).

Remarks

This structure is passed in to the IFilterMapper2::RegisterFilter method.

Set dwVersion to 1 if you are using the old format, or to 2 if you need mediums and pin categories.
