Overview
Tspi_Context_GetTpmObject retrieves the TPM object of a context. Only one instance of this object exists for a given context and implicitly represents a TPM owner. This function is normally called at the beginning of a program, right after the context is established. You must have a context established prior to calling this function.
Parameters
hContext
The hContext parameter is the handle of the context object (already existing).
phTPM
The phTPM parameter is a pointer to where the handle of the TPM will be placed.
Return codes
Tspi_Context_GetTpmObject 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
|

TSS_E_BAD_PARAMETER
