modern C++: write my own function that returns true / false, and a value, part 2 (embedded friendly)

code in action, for a Raspberry Pico GPS design:

19 satellites in view from my back window. The parser mechanism described above is used. stl algorithms split the found satellites into glonass and gps types.

Nice post Jan.

I like the idea of getting multiple types of information directly from functions.

I flagged this as embedded friendly, but there is a caveat for ARM controllers:

It needs C++ 15. If you are using a Raspberry Pico 2, in RISC-V mode, it will work. GCC15 is released for that.

But as of today, there is no published ARM GCC 15 toolchain. If the OpenArm initiative sticks to its schedule, a version 15 release is imminent...
