Function Documentation

◆ _IRQL_requires_max_()

WDF_EXTERN_C_START typedef _Must_inspect_result_ _IRQL_requires_max_ ( PASSIVE_LEVEL  )

Queries information details about a security descriptor.

Computes the quota size of a security descriptor.

Assigns a security descriptor for a new object.

An extended function that assigns a security descriptor for a new object.

Frees a security descriptor.

An extended function that sets new information data to a security descriptor.

Modifies some information data about a security descriptor.

Parameters
[in]SecurityInformationSecurity information details to be queried from a security descriptor.
[out]SecurityDescriptorThe returned security descriptor with security information data.
[in,out]LengthThe returned length of a security descriptor.
[in,out]ObjectsSecurityDescriptorThe returned object security descriptor.
Returns
Returns STATUS_SUCCESS if the operations have been completed successfully and that the specific information about the security descriptor has been queried. STATUS_BUFFER_TOO_SMALL is returned if the buffer size is too small to contain the queried info about the security descriptor.
Parameters
[in]ObjectIf specified, the function will use this arbitrary object that points to an object security descriptor.
[in]SecurityInformationSecurity information details to be set.
[in]SecurityDescriptorA security descriptor where its info is to be changed.
[in,out]ObjectsSecurityDescriptorThe returned pointer to security descriptor objects.
[in]PoolTypePool type for the new security descriptor to allocate.
[in]GenericMappingThe generic mapping of access rights masks.
Returns
See SeSetSecurityDescriptorInfoEx.
Parameters
[in]ObjectIf specified, the function will use this arbitrary object that points to an object security descriptor.
[in]SecurityInformationSecurity information details to be set.
[in]SecurityDescriptorA security descriptor where its info is to be changed.
[in,out]ObjectsSecurityDescriptorThe returned pointer to security descriptor objects.
[in]AutoInheritFlagsFlags bitmask inheritation, influencing how the security descriptor can be inherited and if it can be in the first place.
[in]PoolTypePool type for the new security descriptor to allocate.
[in]GenericMappingThe generic mapping of access rights masks.
Returns
Returns STATUS_SUCCESS if the operations have been completed without problems and that new info has been set to the security descriptor. STATUS_NO_SECURITY_ON_OBJECT is returned if the object does not have a security descriptor. STATUS_INSUFFICIENT_RESOURCES is returned if memory pool allocation for the new security descriptor with new info set has failed.
Parameters
[in]SecurityDescriptorA security descriptor to be freed from memory.
Returns
Returns STATUS_SUCCESS.
Parameters
[in]_ParentDescriptorA security descriptor of the parent object that is being created.
[in]_ExplicitDescriptorAn explicit security descriptor that is applied to a new object.
[out]NewDescriptorThe new allocated security descriptor.
[in]ObjectTypeThe type of the new object.
[in]IsDirectoryObjectSet this to TRUE if the newly created object is a directory object, otherwise set this to FALSE.
[in]AutoInheritFlagsAutomatic inheritance flags that influence how access control entries within ACLs from security descriptors are inherited.
[in]SubjectContextSecurity subject context of the new object.
[in]GenericMappingGeneric mapping of access mask rights.
[in]PoolTypeThis parameter is unused.
Returns
Returns STATUS_SUCCESS if the operations have been completed successfully and that the security descriptor has been assigned to the new object. STATUS_NO_TOKEN is returned if the caller hasn't supplied a valid argument to a security subject context. STATUS_INVALID_OWNER is returned if the caller hasn't supplied a parent descriptor that belongs to the main user (owner). STATUS_INVALID_PRIMARY_GROUP is returned by the same reason as with the previous NTSTATUS code. The two NTSTATUS codes are returned if the calling thread stated that the owner and/or group is defaulted to the parent descriptor (SEF_DEFAULT_OWNER_FROM_PARENT and/or SEF_DEFAULT_GROUP_FROM_PARENT respectively). STATUS_INSUFFICIENT_RESOURCES is returned if memory pool allocation for the descriptor buffer has failed. A failure NTSTATUS is returned otherwise.
Parameters
[in]ParentDescriptorA security descriptor of the parent object that is being created.
[in]ExplicitDescriptorAn explicit security descriptor that is applied to a new object.
[out]NewDescriptorThe new allocated security descriptor.
[in]IsDirectoryObjectSet this to TRUE if the newly created object is a directory object, otherwise set this to FALSE.
[in]SubjectContextSecurity subject context of the new object.
[in]GenericMappingGeneric mapping of access mask rights.
[in]PoolTypeThis parameter is unused.
Returns
See SeAssignSecurityEx.
Parameters
[in]SecurityDescriptorA security descriptor.
[out]QuotaInfoSizeThe returned quota size of the given security descriptor to the caller. The function may return 0 to this parameter if the descriptor doesn't have a group or a discretionary access control list (DACL) even.
Returns
Returns STATUS_SUCCESS if the quota size of a security descriptor has been computed successfully. STATUS_UNKNOWN_REVISION is returned if the security descriptor has an invalid revision.
