FwpmConnectionGetSecurityInfo0 function (fwpmu.h)

  • Article

The FwpmConnectionGetSecurityInfo0 function retrieves a copy of the security descriptor for a connection object change event.

Syntax

DWORD FwpmConnectionGetSecurityInfo0(
  [in]  HANDLE               engineHandle,
  [in]  SECURITY_INFORMATION securityInfo,
  [out] PSID                 *sidOwner,
  [out] PSID                 *sidGroup,
  [out] PACL                 *dacl,
  [out] PACL                 *sacl,
  [out] PSECURITY_DESCRIPTOR *securityDescriptor
);

Parameters

[in] engineHandle

Type: HANDLE

Handle for an open session to the filter engine. Call FwpmEngineOpen0 to open a session to the filter engine.

[in] securityInfo

Type: SECURITY_INFORMATION

The type of security information to retrieve.

[out] sidOwner

Type: PSID*

The owner security identifier (SID) in the returned security descriptor.

[out] sidGroup

Type: PSID*

The primary group security identifier (SID) in the returned security descriptor.

[out] dacl

Type: PACL*

The discretionary access control list (DACL) in the returned security descriptor.

[out] sacl

Type: PACL*

The system access control list (SACL) in the returned security descriptor.

[out] securityDescriptor

The returned security descriptor.

Return value

Type: DWORD

Return code/value Description
ERROR_SUCCESS
0
 The security descriptor was successfully retrieved.
FWP_E_* error code
0x80320001—0x80320039
 A Windows Filtering Platform (WFP) specific error. See WFP Error Codes for details.
RPC_* error code
0x80010001—0x80010122

Remarks

The returned securityDescriptor parameter must be freed through a call to FwpmFreeMemory0. The other four returned parameters must not be freed, as they point to addresses within the securityDescriptor parameter.

This function behaves like the standard Win32 GetSecurityInfo function. The caller needs the same standard access rights as described in the GetSecurityInfo reference topic.
