that connects to the RPC interface of the Firewall and Advanced Security
Protocol.</p><p><b>hPolicyStore: </b>An input parameter that is an <b>FW_POLICY_STORE_HANDLE</b>
data type. This parameter MUST contain an opened policy store handle,
successfully opened with the RRPC_FWOpenPolicyStore (Opnum 0) method (section <span><a href="2157e39a-1bf0-4e0c-abae-0811fd918b11" data-linktype="relative-path">3.1.4.1</a></span>).
The handle MUST have read/write access rights.</p><p><b>dwFilteredByStatus: </b>A combination of flags
from the <b>FW_RULE_STATUS_CLASS</b> enumeration. This method uses this bitmask
to determine which rules will be returned. Rules that contain a status code of
the specified class that match this parameter will be returned in the linked
list.</p><p><b>dwProfileFilter: </b>A combination of flags from
the <b>FW_PROFILE_TYPE</b> enumeration. This method also uses this parameter to
determine which rules will be returned. Rules that contain a profile specified
by this parameter will be returned in the linked list.</p><p><b>wFlags: </b>A combination of flags from the <b>FW_ENUM_RULES_FLAGS</b>
enumeration, which modifies the behavior of the method and performs operations
on the rules before returning them in the linked list.</p><p><b>pdwNumRules: </b>An output parameter that, on
success, MUST be equal to the number of rules returned.</p><p><b>ppRules: </b>An output parameter that, on success,
contains a linked list of <b>FW_RULE2_24</b> data types.</p><p><b>Return Values: </b>The method returns 0 if
successful; if it fails, it returns a nonzero error code. The field can take
any specific error code value, as specified in <span><a href="../ms-erref/1bc92ddf-b79e-413c-bbaa-99a5281a6c90" data-linktype="relative-path">[MS-ERREF]</a></span>.
