CreatePrivateObjectSecurity

The CreatePrivateObjectSecurity function allocates and initializes a self-relative security descriptor for a new private object. A protected server calls this function when it creates a new private object.

To specify the object type GUID of the new object or control how ACEs are inherited, use the CreatePrivateObjectSecurityEx function.

BOOL CreatePrivateObjectSecurity(
  PSECURITY_DESCRIPTOR ParentDescriptor,  // parent directory SD
  PSECURITY_DESCRIPTOR CreatorDescriptor, // creator SD
  PSECURITY_DESCRIPTOR *NewDescriptor,    // new SD
  BOOL IsDirectoryObject,                 // container
  HANDLE Token,                           // handle to access token
  PGENERIC_MAPPING GenericMapping         // mapping
);

Parameters

ParentDescriptor

[in] Pointer to the security descriptor for the parent directory in which a new object is being created. If there is no parent directory, this parameter can be NULL.

CreatorDescriptor

[in] Pointer to a security descriptor provided by the creator of the object. If the object's creator does not explicitly pass security information for the new object, this parameter is intended to be NULL.

NewDescriptor

[out] Pointer to a variable that receives a pointer to the newly allocated self-relative security descriptor. The caller must call the DestroyPrivateObjectSecurity function to free this security descriptor.

IsDirectoryObject

[in] Specifies whether the new object is a container. A value of TRUE indicates the object contains other objects, such as a directory.

Token

[in] Handle to the access token for the client process on whose behalf the object is being created. If this is an impersonation token, it must be at SecurityIdentification level or higher. For a full description of the SecurityIdentification impersonation level, see the SECURITY_IMPERSONATION_LEVEL enumerated type.

A client token is used to retrieve default security information for the new object, such as its default owner, primary group, and discretionary access-control list. The token must be open for TOKEN_QUERY access.

GenericMapping

[in] Pointer to a GENERIC_MAPPING structure that specifies the mapping from each generic right to specific rights for the object.

Return Values

If the function succeeds, the return value is nonzero.

If the function fails, the return value is zero. To get extended error information, call GetLastError.

Remarks

If a system access-control list, or SACL, is specified in the SECURITY_DESCRIPTOR specified by the CreatorDescriptor parameter, the Token parameter must have the SE_SECURITY_NAME privilege enabled. The CreatePrivateObjectSecurity function checks this privilege and may generate audits during the process.

Requirements

  Windows NT/2000: Requires Windows NT 3.1 or later.
  Header: Declared in Winbase.h; include Windows.h.
  Library: Use Advapi32.lib.
