Mac OS X Lion: What is the max path length?

Question

I am having trouble finding this information, and trial and error is telling me that the value is very high. I figured I would ask the community to see if anyone knows and can point me to an apple page that confirms the length for Lion. All I know is it is larger that Snow Leopard.

Answer 1

Old, but I found an answer:

#include <sys/syslimits.h>

and then it'll have a PATH_MAX constant as a #define. In my case,

char filenameBuffer [PATH_MAX];

You could hardcode 1024 as the maximum path, but using a constant like that makes your code scalable with new releases
