Description

The FwpmConnectionCreateEnumHandle0 function creates a handle used to enumerate a set of connection objects.

enumTemplate [in, optional]

Template for selectively restricting the enumeration.

enumHandle [out]

Address of a HANDLE variable. On function return, it contains the handle for the enumeration.
