3.1.4.9 RRPC_FWDeleteAllFirewallRules (Opnum 8)

The RRPC_FWDeleteAllFirewallRules method deletes all firewall rules in the firewall linked list of the memory representation of the store being modified. It also writes through and deletes all rules from the disk representation. If called on an online store, no firewall rules are enforced after the method returns.

 unsigned long RRPC_FWDeleteAllFirewallRules(
   [in] FW_CONN_HANDLE rpcConnHandle,
   [in] FW_POLICY_STORE_HANDLE hPolicyStore
 );

rpcConnHandle: This parameter is an RPC binding handle that connects to the RPC interface of the Firewall and Advanced Security Protocol.

hPolicyStore: This input parameter is an FW_POLICY_STORE_HANDLE data type. The data type MUST contain an opened policy store handle, successfully opened with the RRPC_FWOpenPolicyStore (Opnum 0) method. The handle MUST have read/write access rights.

Return Values: The method returns 0 if successful; if failed, it returns a nonzero error code. The field can take any specific error code value, as specified in [MS-ERREF]. The following are common.

Return value/code	Description
0x00000032 ERROR_NOT_SUPPORTED	The specified store does not support this method; the store might be read-only.
0x00000005 ERROR_ACCESS_DENIED	The hPolicyStore handle was not opened with read/write access rights. The error is also returned if the client does not have the required credentials to call the method.

Exceptions Thrown: No exceptions are thrown beyond those thrown by the underlying RPC protocol, as specified in [MS-RPCE]. If any lower-layer errors are reported by RPC exception, this exception is converted to an error code and reported to higher-layer protocols via the return value.

The server MUST validate that the client is authorized to perform the requested operation (as defined in section 3.1.4) before executing this method.
