Just a bit confused about what all these are, and the differences between them.
I believe that the reason for 2 such similar constants is their historic origins - MAXPATHLEN originally from the Unix world, and MAX_PATH from the Windows world. I do most of my work on both Linux and macOS, ensuring that my code compiles with minimal reference to its environment. With this, I always just include sys/param.h and use MAXPATHLEN. On Ubuntu 23.04, today, the value is 4096; on macOS 14.0.1 it is 1024.
