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.
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;
}
#define one of the following
#define _POSIX_SOURCE
#define _POSIX_C_SOURCE 1 /* or any value larger then 1 */
#define _XOPEN_SOURCE
before #includeing <limits.h>and the compiler will see _POSIX_PATH_MAX.
You also can specify this on the command line via the compiler option -D:
gcc -c main.c -D_POSIX_C_SOURCE=1
for example.
