Haven't used this forum much this project haha but now I finally found a question (kinda) to bother you with. Before I read the post titled Macro Definitions, I was searching up the maximum path names in Linux systems. I stumbled across MAX_PATH which is defined in <limits.h> which is defined to be 4096 bytes. However, for MAX_PATH to be defined, I also had to use #define _POSIX_C_SOURCE 200809L. I also found that MAX_PATH was defined in <sys/param.h> and is the same number as MAXPATHLEN. Just a bit confused about what all these are, and the differences between them.
