TSS2_RC Fapi_SetSignCB (FAPI_CONTEXT *context, Fapi_CB_Sign callback, void *userData)
TSS2_RC Fapi_SetPolicyActionCB (FAPI_CONTEXT *context, Fapi_CB_PolicyAction callback, void *userData)

Fapi_SetActionCB() registers an application-defined function as a callback that shall be called back upon encountering a policy action element.

Parameters

context The FAPI_CONTEXT
callback The callback function for branch selection
userData A pointer that is provided to all callback invocations

Return values

TSS2_RC_SUCCESS if the function call was a success.
TSS2_FAPI_RC_BAD_REFERENCE if the context is NULL.
TSS2_FAPI_RC_BAD_CONTEXT if context corruption is detected.
TSS2_FAPI_RC_MEMORY if the FAPI cannot allocate enough memory for internal operations or return parameters.
TSS2_FAPI_RC_BAD_SEQUENCE if the synchronous or Async functions are called while the context has another asynchronous operation outstanding, or the Finish function is called while the context does not have an appropriate asynchronous operation outstanding.
TSS2_FAPI_RC_IO_ERROR if the data cannot be saved.

Fapi_SetSignCB() registers an application-defined function as a callback to allow the FAPI to get signatures authorizing use of TPM objects.

Parameters

context The FAPI_CONTEXT

userData A pointer that is provided to all callback invocations

Return values

TSS2_RC_SUCCESS if the function call was a success.
TSS2_FAPI_RC_BAD_REFERENCE if the context is NULL.
TSS2_FAPI_RC_BAD_CONTEXT if context corruption is detected.
TSS2_FAPI_RC_MEMORY if the FAPI cannot allocate enough memory for internal operations or return parameters.
TSS2_FAPI_RC_BAD_SEQUENCE if the synchronous or Async functions are called while the context has another asynchronous operation outstanding, or the Finish function is called while the context does not have an appropriate asynchronous operation outstanding.
TSS2_FAPI_RC_IO_ERROR if the data cannot be saved.
