MULTICAST_MODE_TYPE enumeration

The MULTICAST_MODE_TYPE enumeration specifies the filter mode for multicast group addresses.

Syntax


typedef enum  { 
  MCAST_INCLUDE  = 0,
  MCAST_EXCLUDE
} MULTICAST_MODE_TYPE;

Constants

MCAST_INCLUDE

The filter contains a list of IP addresses to include.

MCAST_EXCLUDE

The filter contains a list of IP addresses to exclude.

Remarks

This enumeration is supported on Windows Vista and later.

The MULTICAST_MODE_TYPE enumeration is used in the gf_fmode member of the GROUP_SOURCE_REQ structure to determine if a list of IP addresses should included or excluded. The values from this enumeration can also be used in the imsf_fmode member of the ip_msfilter structure.

The MULTICAST_MODE_TYPE enumeration is defined in the Ws2ipdef.h header file which is automatically included in the Ws2tcpip.h header file. The Ws2ipdef.h header files should never be used directly.
