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.
