 **TSS\_RESULT Tspi\_TPM\_Quote(TSS\_HTPM**  *hTPM***,          TSS\_HKEY**        *hIdentKey***,**
                           **TSS\_HPCRS** *hPcrComposite***, TSS\_VALIDATION\*** *pValidationData***);**

## DESCRIPTION

**Tspi\_TPM\_Quote** destroys a context by passing in the handle to that context.

## PARAMETERS

### hTPM

Handle of the TPM object.

### hIdentKey

Handle of the signature key object.

### hPcrComposite

Handle of the PCR composite object

### pValidationData

Validation data structure
 \[IN\] Provide externalData information required to compute the signature.
 \[OUT\] On successful completion of the command, the structure provides a buffer containing the validation data and a buffer containing the data the validation data was computed form.

## RETURN CODES

**Tspi\_TPM\_Quote** returns TSS\_SUCCESS on success, otherwise one of the following values are returned:
 TSS\_E\_INVALID\_HANDLE - *hTPM*, *hIdentKey* or *hPcrComposite* is not a valid handle.
 TSS\_E\_BAD\_PARAMETER
 TSS\_E\_INTERNAL\_ERROR - An error occurred internal to the TSS.

## CONFORMING TO

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