How to determine system value for _POSIX_PATH_MAX

Question

Can anyone please tell me how to find the system value for _POSIX_PATH_MAX in Linux mint? I know that it is available in the <limits.h> file but I do not know how to find its value.

Answer 1

The tool to use, according to POSIX, is named getconf(1):

  $ getconf _POSIX_PATH_MAX
  256

Answer 2

One more way to get it's value.

#include "stdio.h"
#include "unistd.h"
#include "limits.h"

int main()
{
    printf ("Value :: %d \n", _POSIX_PATH_MAX);
    return 0;
}
