Could not enable input device(s)

[Ron]

__declspec(dllexport) bool start_device()

Start device returns a bool...

Are some of the documents in err on this subject ? If so let me know where.

return TRUE when plugin started succesfully, return FALSE when plugin didn't start succesfully.

I'm creating a new plugin to send/receive SMS via a mobile phone.

When pressing F9, Girder shows a yellow LED and says 'Initialising input devices', this can take a while. In the meantime my plugin is called via 'start_device' which calls to open a COM port session with the GSM (async, takes a while) and initiates a command to it.

After a few seconds Girder shows a red LED and 'Could not enable input device(s)' and my plugin is called via 'stop_device'.

Although, after a second the initiated command to the GSM finishes and a resulting event is sent to Girder correctly, Girder then shows a blue LED.

Ron, can you explain how you determine whether enabling has failed/succeeded as 'start_device' returns nothing (void) !!!

Well the V32 documentation indeed states the BOOL return value, however you do NOT specify what should be returned.

For following functions the documentation is not sufficient:

1) h_support_functions: it does not say Girder first calls it with a NULL pointer to obtain the version of the HW support functions. Then calls it with a valid pointer from which you have to copy the referred structure into the plugin.

2) start_device/stop_device: it does not say what to return. Can you pls clarify this!?


I must say that my other plugins DO work, even with the void declaration!?!?!?
