GetAccessPermissionsForObject info  Overview  Group

[This is a preview of an interface that may appear in future releases of Windows.]

The GetAccessPermissionsForObject function determines the access rights supported by a specified object.

DWORD GetAccessPermissionsForObject(

Parameters

lpObject

Pointer to a null-terminated string that specifies the name of the object for which to get the list of supported access rights. For descriptions of the string formats for the different object types, see SE_OBJECT_TYPE.

ObjectType

Specifies a value from the SE_OBJECT_TYPE enumeration that indicates the type of object named by the lpObject parameter.

lpProvider

Pointer to a null-terminated string that specifies the name of the provider to handle the request. If this parameter is NULL, the system determines the proper provider to handle the request.

pcEntries

Pointer to a ULONG value that receives the number of entries returned in the ppAccessInfoList array.

ppAccessInfoList

Pointer to a variable that receives a pointer to an array of ACTRL_ACCESS_INFO structures. Each entry identifies an access right supported by the object. Call the LocalFree function to free the returned buffer.

pfAccessFlags

Pointer to a ULONG value that can receive the following access flag.

Value	Meaning
ACTRL_ACCESS_SUPPORTS_OBJECT_ENTRIES
	The object's provider supports setting access-control entries on the object's properties, and it also supports propagating inherited entries to child objects.

Return Values

If the function succeeds, the return value is ERROR_SUCCESS.

If the function fails, the return value can be one of the following error codes.

Remarks

The GetAccessPermissionsForObject function returns an array of ACTRL_ACCESS_INFO structures to indicate the access rights an object supports. For example, the array for an SE_FILE_OBJECT object type might include the following access rights and string descriptions.

{ACTRL_SYNCHRONIZE, “Synchronize”},

{ACTRL_CHANGE_OWNER, “Change Owner”},

{ACTRL_CHANGE_ACCESS, “Change Access”},

…

{ACTRL_FILE_READ, “Read File”},

{ACTRL_FILE_WRITE, “Write File”}

…

Currently, the import library for the GetAccessPermissionsForObject function is ACCSRC.LIB. This is temporary. Eventually, the import library will be ADVAPI32.LIB. Meanwhile, any source code that links with the ACCSRC.LIB library must call the AccProvInit macro as follows:

    DWORD dwErrcode;



    AccProvInit(dwErrcode);

    if(dwErrcode != ERROR_SUCCESS)

    {

         // Consider this an error...

    }
