I am interested in using the library but could not find much documentation. The example is not very helpful either if you don't even know how the library works.
It would be nice to have some more examples (that also have descriptions) and to have an API documentation (maybe generated by doxygen or some similar software).
These should also be linked in the readme so that new developers can get started without many problems.

I built the lib on Raspian - hand installed includes and libs in /usr/local

My attempts to compile example.cpp report missing symbols when linked with either/or/both LIOlib & LIOLinuxlib

i.e.
g++ -L/usr/local/lib -lLIOLinuxlib -lLIOlib example.o
-o example

Hi,

Can this be used to add a push button (input) and a led (output) to a Jetson Xavier GPIO using c++?

(tried to label as question rather than issue but don't know how sorry)

thanks

problem during edge set on RPI4

internal state changes should be independent from the callbacks
