PATH_MAX = 4k ?

Is PATH_MAX really that big or do I have something wrong?

What tools are you using to get that value and assuming you are on one of the UNIX's are you using the getconf utility?

oh I just did this:

Code:

---

printf("%d\n", PATH_MAX);

---

What OS platform are you on? Show the entire code instead of just the printf() statement.

I think it must have been:

Code:

---

#include <linux/limits.h>
#include <stdio.h>

int main () {
    printf("%d\n", PATH_MAX);
}

I doubt it's lying... PATH_MAX is only a hint, anyway, since the underlying platform might have no path length limitation at all. And there's no way to indicate that fact with some finite number, so they just pick a large number at random...

So then 4k is correct as the PATH_MAX symbolic constant is defined in the <limits.h> include file on Unix/Linux.
So there you can have deeply nested directories and/or really long names for them.

that's not a nest, it's obscene

cool beans ;)

Original DOS was 8.3 and no subdirectories, and people complained it was too little.
Now 4K is too much, and people complain it's too much.
*shrug*

4k is perfectly reasonable for a path. I suppose this is under Linux?
