handle :
the handle
update :
the callbacks to use
Return value :
0 if successful, an error code otherwise.

ticalcs_update_get

TIEXPORT3 CalcUpdate* TICALL ticalcs_update_get(CalcHandle *handle)

Get the update callbacks used for the given handle.

handle :
the handle
Return value :
the update struct pointer or NULL.

ticalcs_model_supports_dbus

{

Returns whether the given calculator model supports the protocol dubbed DBUS by libticalcs. That is, the standard protocol used by TI-Z80 and TI-68k calculators over the legacy I/O.

model :
a calculator model taken in #CalcModel.
Return value :
nonzero if the calculator supports the DBUS protocol, zero if it doesn't.

ticalcs_model_supports_dusb

{

Returns whether the given calculator model supports the CARS protocol dubbed DUSB by libticalcs. That is, the standard protocol used by TI-Z80, TI-eZ80 and TI-68k calculators over the USB port.

model :
a calculator model taken in #CalcModel.
Return value :
nonzero if the calculator supports the DUSB protocol, zero if it doesn't.

ticalcs_model_supports_nsp

{

Returns whether the given calculator model supports the NavNet protocol dubbed NSP by libticalcs. That is, the standard protocol used by TI-Nspire calculators over the USB port.

model :
a calculator model taken in #CalcModel.
Return value :
nonzero if the calculator supports the NSP protocol, zero if it doesn't.

ticalcs_model_supports_installing_flashapps

{

Returns whether the given calculator model supports transferring additional FlashApps to the calculator. Some models support FlashApps only as an integral part of the OS upgrade image, arbitrary FlashApps can't be transferred.

model :
a calculator model taken in #CalcModel.
Return value :
nonzero if the calculator supports installing additional FlashApps onto the calculator, zero if it doesn't.

ticalcs_calc_get_event_hook

{
