Getting system's max allowed path length in c

Question

How can I determine the maximum file path length allowed in the system my program is running on? Is it in limits.h? because I didn't find it there.

[Where is PATH_MAX defined in Linux?](https://stackoverflow.com/a/56385296/24103599) may be useful. — chux - Reinstate Monica, May 09 '20 at 08:03

It should be NAME_MAX defined in <limits.h>

It says that this is an implementation - defined constant – avivgood2 May 09 '20 at 06:39
yeah usually it's on Linux system, not sure if it's also the same for Windows or MacOS – artm May 09 '20 at 06:42
@avivgood2 Yes, implementation-defined is a good as it gets. It means the implementation must provide a document stating the value (and limits.h contents may be enough for that). NAME_MAX is not constant across the universe, as say, the speed of light. :-) – Jens May 09 '20 at 10:59
