#include <tss/tcpa_defines.h>
#include <tss/tcpa_typedef.h>
#include <tss/tcpa_struct.h>

TSS_RESULT Tspi_SetAttribUint32(TSS_HOBJECT hObject, TSS_FLAG attribFlag,
                                TSS_FLAG    subFlag, UINT32   ulAttrib);
```

## DESCRIPTION

**Tspi\_SetAttribUint32** sets a uint32 attribute associated with a given class or object. In order to use this command, you must first create an object and then find the attributes you wish to set.

## PARAMETERS

### hObject

The *hObject* parameter is the handle of the object or class whose attributes are being set. Note that this is any object handler - context, policy, TPM, key, hash, etc.

### attribFlag

The *attribFlag* parameter indicates the specific attribute to be set.

### subFlag

The *subFlag* parameter also indicates the specific attribute to be set.

### ulAttrib

The *ulAttrib* parameter is the value that the specified attribute will be set to.

## RETURN CODES

**Tspi\_SetAttribUint32** returns TSS\_SUCCESS on success, otherwise one of the following values is returned:

- TSS\_E\_INVALID\_HANDLE

  *hObject* is not a valid handle.

- TSS\_E\_INVALID\_ATTRIB\_FLAG

  *attribFlag* is incorrect.

- TSS\_E\_INVALID\_ATTRIB\_SUBFLAG

  *subFlag* is incorrect.

- TSS\_E\_INVALID\_ATTRIB\_DATA

  *ulAttrib* is incorrect.

- TSS\_E\_INTERNAL\_ERROR

  An internal SW error has been detected.

- TSS\_E\_BAD\_PARAMETER

  One or more parameters is bad.

## CONFORMING TO

**Tspi\_SetAttribUint32** conforms to the Trusted Computing Group Software Specification version 1.1 Golden
