TSS_RESULT Tspi_GetAttribData(TSS_HOBJECT hObject, TSS_FLAG attribFlag,
                              TSS_FLAG    subFlag, UINT32*  pulAttribDataSize,

Tspi_GetAttribData is used to get the value of a particular attribute associated iwth a particular object where that attribute does not happen to be a UINT32. The structure and size of the attribute data depends on the attribute.

hObject

Handle of the object where to retrieve the attribute.

attribFlag

Flag indicating the attribute to query.

subFlag

Sub flag indicating the attribute to query.

pulAttribDataSize

Recieves the length (in bytes) of the prgbAttribData parameter.

prgbAttribData

On successful completion of the command, this parameter points to a buffer containing the actual data of the specified attribute.

Tspi_GetAttribData returns TSS_SUCCESS on success, otherwise one of the following values are returned:

TSS_E_INVALID_HANDLE - Either hObject, attribFlag, or subFlag are invalid.

TSS_E_ATTRIB_FLAG

TSS_E_ATTRIB_SUBFLAG

TSS_E_ATTRIB_DATA

TSS_E_BAD_PARAMETER

TSS_E_INTERNAL_ERROR - An error occurred internal to the TSS.

Tspi_GetAttribData conforms to the Trusted Computing Group Software Specification version 1.1 Golden
