Which header file should I invoke with #include
to be able to use PATH_MAX as an int for sizing a string?
I want to be able to declare:
char *current_path[PATH_MAX];
But when I do so my compiler (Clang/LLVM on Linux) issues the following error:
recursive_find6.c:29:20: error: use of undeclared identifier 'PATH_MAX' char *current_path[PATH_MAX]; ^
I tried doing a google search but still no luck.
#include <limits.h>
Does NOT fix the problem/error.
Am I also correct that the value of PATH_MAX is an int?

Answer
Its in linux/limits.h
.
#define PATH_MAX 4096 /* # chars in a path name including nul */
#include <linux/limits.h> char current_path[PATH_MAX];
PATH_MAX
has some flaws as mentioned in this blog (thanks paulsm4)
