AtlGetDacl

Call this function to retrieve the discretionary access-control list (DACL) information of a specified object.

Important

This function cannot be used in applications that execute in the Windows Runtime.

inline bool AtlGetDacl(
    HANDLE hObject,
    SE_OBJECT_TYPE ObjectType,
    CDacl* pDacl) throw();

Parameters

hObject
Handle to the object for which to retrieve the security information.

ObjectType
Specifies a value from the SE_OBJECT_TYPE enumeration that indicates the type of object identified by the hObject parameter.

pDacl
Pointer to a DACL object which will contain the retrieved security information.

Return Value

Returns true on success, false on failure.

Remarks

In debug builds, an assertion error will occur if either hObject or pDacl is invalid.

Return Value

Returns true on success, false on failure.

Remarks

In debug builds, an assertion error will occur if hObject is invalid, or if dwInheritanceFlowControl is not one of the three permitted values.

Handle to the object for which to set security information.

ObjectType
Specifies a value from the SE_OBJECT_TYPE enumeration that indicates the type of object identified by the hObject parameter.

rSid
The CSid object containing the new security information.

Return Value

Returns true on success, false on failure.

Requirements

Header: atlsecurity.h

AtlGetOwnerSid

Call this function to retrieve the owner security identifier (SID) of an object.

Important

This function cannot be used in applications that execute in the Windows Runtime.

inline bool AtlGetOwnerSid(
    HANDLE hObject,
    SE_OBJECT_TYPE ObjectType,
    CSid* pSid) throw(...);

Parameters

hObject
Handle to the object from which to retrieve security information.

ObjectType
Specifies a value from the SE_OBJECT_TYPE enumeration that indicates the type of object identified by the hObject parameter.

pSid
Pointer to a CSid object which will contain the new security information.

Return Value

Returns true on success, false on failure.

Requirements

Header: atlsecurity.h

AtlSetOwnerSid

Call this function to set the owner security identifier (SID) of an object.

Important

This function cannot be used in applications that execute in the Windows Runtime.

inline bool AtlSetOwnerSid(
    HANDLE hObject,
    SE_OBJECT_TYPE ObjectType,
    const CSid& rSid) throw(...);

Parameters

hObject
Handle to the object for which to set security information.

ObjectType
Specifies a value from the SE_OBJECT_TYPE enumeration that indicates the type of object identified by the hObject parameter.

rSid
The CSid object containing the new security information.

Return Value

Returns true on success, false on failure.

Requirements

Header: atlsecurity.h

AtlGetSacl

Call this function to retrieve the system access-control list (SACL) information of a specified object.

Important

This function cannot be used in applications that execute in the Windows Runtime.

inline bool AtlGetSacl(
    HANDLE hObject,
    SE_OBJECT_TYPE ObjectType,
    CSacl* pSacl,
    bool bRequestNeededPrivileges = true) throw(...);

Parameters

hObject
Handle to the object from which to retrieve the security information.

ObjectType
Specifies a value from the SE_OBJECT_TYPE enumeration that indicates the type of object identified by the hObject parameter.

bRequestNeededPrivileges
If true, the function will attempt to enable the SE_SECURITY_NAME privilege, and restore it on completion.

Return Value

Returns true on success, false on failure.

Remarks

If AtlGetSacl is to be called many times on many different objects, it will be more efficient to enable the SE_SECURITY_NAME privilege once before calling the function, with bRequestNeededPrivileges set to false.

Header: atlsecurity.h

AtlSetSacl

Call this function to set the system access-control list (SACL) information of a specified object.

Important

This function cannot be used in applications that execute in the Windows Runtime.

inline bool AtlSetSacl(
    HANDLE hObject,
    SE_OBJECT_TYPE ObjectType,
    const CSacl& rSacl,
    DWORD dwInheritanceFlowControl = 0,
    bool bRequestNeededPrivileges = true) throw(...);

ObjectType
Specifies a value from the SE_OBJECT_TYPE enumeration that indicates the type of object identified by the hObject parameter.

rSacl
The SACL containing the new security information.

dwInheritanceFlowControl
The inheritance flow control. This value can be 0 (the default), PROTECTED_SACL_SECURITY_INFORMATION or UNPROTECTED_SACL_SECURITY_INFORMATION.

bRequestNeededPrivileges

Returns true on success, false on failure.

Remarks

In debug builds, an assertion error will occur if hObject is invalid, or if dwInheritanceFlowControl is not one of the three permitted values.

AtlGetSecurityDescriptor

Call this function to retrieve the security descriptor of a given object.

Important

This function cannot be used in applications that execute in the Windows Runtime.

inline bool AtlGetSecurityDescriptor(
    LPCTSTR pszObjectName,
    SE_OBJECT_TYPE ObjectType,
    CSecurityDesc* pSecurityDescriptor,
    SECURITY_INFORMATION requestedInfo = OWNER_SECURITY_INFORMATION |
    GROUP_SECURITY_INFORMATION | DACL_SECURITY_INFORMATION |

bool bRequestNeededPrivileges = true) throw(...);

Parameters

pszObjectName
Pointer to a null-terminated string that specifies the name of the object from which to retrieve security information.

ObjectType
Specifies a value from the SE_OBJECT_TYPE enumeration that indicates the type of object identified by the pszObjectName parameter.

pSecurityDescriptor
The object which receives the requested security descriptor.

requestedInfo
A set of SECURITY_INFORMATION bit flags that indicate the type of security information to retrieve. This parameter can be a combination of the following values.
