TSS_RESULT Tspi_GetPolicyObject(TSS_HOBJECT hObject, TSS_FLAG policyType,
TSS_HPOLICY* phPolicy);
Tspi_GetPolicyObject returns a policy object currently assigned to a
working object. If you determine that the policy is different from what you
require, you can change the policy by creating a new one and using
Tspi_Policy_AssignToObject.
The hObject parameter is the handle of the object.
The policyType parameter indicates the policy type of interest. Types are
TSS_POLICY_USAGE and TSS_POLICY_MIGRATION.
The phPolicy parameter receives the handle to the assigned policy object.
Tspi_GetPolicyObject returns TSS_SUCCESS on success, otherwise one of the
following values is returned:
- TSS_E_INVALID_HANDLE
- hContext is not a valid handle.
- TSS_E_INTERNAL_ERROR
- An internal SW error has been detected.
- TSS_E_BAD_PARAMETER
- One or more parameters is bad.
