Use LwPRINTF as output for LwSHELL

[effemmeffe]

I noticed that LwSHELL has the option to define an output and I was wondering if I can somehow use LwPRINTF since I already have it in my code for debug output.
Is there any care I have to take or can I simply invoke
lwshell_set_output_fn(lwprintf);
and get away with it?

You will need to make a wrapper function that calls lwprintf_xx function then.

Sorry, I don't understand what you mean with wrapper.
The lwshell_set_output_fn is used to somehow point to a project specific function that will handle the print, why can't be simply lwprintf that function?
I think I'm missing something.

The function footprint is different between lwprintf ones and expected onenfor LwSHELL output function.

They accept different parameters.

I just noticed that I don't know where to find the prototype for the output function as expected by LwSHELL, can you help me, please?

If you check the footprint of the lwshell_set_output_fn_ex function:

lwshellr_t lwshell_set_output_fn_ex(lwshell_t* lwobj, lwshell_output_fn out_fn);

Then you can find that it accepts the function type lwshell_output_fn which is defined as:

typedef void (*lwshell_output_fn)(const char* str, struct lwshell* lwobj);
