Tspi_Context_RegisterKey - register a key in the TSS Persistent Storage database

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

TSS_RESULT Tspi_Context_RegisterKey(TSS_HCONTEXT hContext,                    TSS_HKEY hKey,
                                    TSS_FLAG     persistentStorageType,       TSS_UUID uuidKey,
                                    TSS_FLAG     persistentStorageTypeParent, TSS_UUID uuidParentKey); 

Tspi_Context_RegisterKey is the API that registers a key with the TSS Persistent Storage database so that it can be loaded as necessary. It also includes all information required for loading the key, as well as information about its parent key.

The hContext parameter is the handle of the context object.

The hKey parameter is the handle of the key object addressing the key to be registered.

The persistentStorageType parameter indicates the persistent storage the key is registered in.

The uuidKey parameter is the UUID by which the key is registered in persistent storage.

The persistentStorageTypeParent parameter indicates the persistent storage that the parent key is registered in.

The uuidParentKey parameter is the UUID by which the parent key is registered in persistent storage.

Tspi_Context_RegisterKey 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_PS_KEY_NOTFOUND
The key cannot be found in the persistent storage database.

TSS_E_INTERNAL_ERROR
An internal SW error has been detected.

TSS_E_BAD_PARAMETER
One or more parameters is bad.
