PFN_FWENUMDYNAMICKEYWORDADDRESSESBYTYPE0 callback function (netfw.h)

  • Article

Function pointer type of the entry point in the service that you call to enumerate dynamic keyword addresses by type. You can request a particular subset of objects based on the enumeration flags passed in.

Note

A pointer type for this free function is published via NetFw.h, but a static-link library isn't published. Use the LoadLibraryExW/GetProcAddress pattern for calling this function.

When you call GetProcAddress, pass a handle to the firewallapi.dll module, and pass FWEnumDynamicKeywordAddressesByType0 as the lpProcName argument.

For more info, and code examples, see Firewall dynamic keywords.
