   Fapi_NvIncrement (FAPI_CONTEXT * context, char const * nvPath)
       One-Call function for Fapi_NvIncrement

       Return values
           TSS2_RC_SUCCESS if the function call was a success.
           TSS2_FAPI_RC_BAD_REFERENCE if context or nvPath is NULL.

           pending.
           TSS2_FAPI_RC_IO_ERROR if the data cannot be saved.

           TSS2_FAPI_RC_BAD_VALUE if an invalid value was passed into the function.
           TSS2_FAPI_RC_TRY_AGAIN if an I/O operation is not finished yet and this function needs
           to be called again.
           TSS2_FAPI_RC_GENERAL_FAILURE if an internal error occurred.
           TSS2_FAPI_RC_AUTHORIZATION_UNKNOWN if a required authorization callback is not set.
           TSS2_FAPI_RC_AUTHORIZATION_FAILED if the authorization attempt fails.
           TSS2_ESYS_RC_* possible error codes of ESAPI.
           TSS2_FAPI_RC_NOT_PROVISIONED FAPI was not provisioned.

   Fapi_NvIncrement_Async (FAPI_CONTEXT * context, char const * nvPath)
       Asynchronous function for Fapi_NvIncrement

       Parameters
           context The FAPI_CONTEXT
           nvPath The path to the NV index that is incremented.

   Fapi_NvIncrement_Finish (FAPI_CONTEXT * context)
       Asynchronous finish function for Fapi_NvIncrement

       This function should be called after a previous Fapi_NvIncrement_Async.

       Parameters
           context The FAPI_CONTEXT

       Return values
           TSS2_RC_SUCCESS if the function call was a success.

           or return parameters.
           TSS2_FAPI_RC_TRY_AGAIN if the asynchronous operation is not yet complete. Call this
           function again later.
