uint64_t might be defined as either unsigned long or unsigned long long, depending on the architecture. Values of this type should be formatted with the specifier PRIu64 rather than "ld".

Hi Ben! This and the other patches are great, thanks! I assume they are rebases on top of the next/libpiod-2.0 branch? I want the git repo for libgpiod to remain bisectable and intend to switch to the new API in one big patch including the core API, C++ and Python bindings as well as test suites. I will keep your patches in my queue and apply them once the patch is in master - unless you don't care that much about authorship of the patches in which case I can squash them into the big patch and credit you in the commit message. Let me know what works best for you. Bart
