linkinfo — Gets information about a link

### Description

linkinfo(string `$path`): int|false

Gets information about a link.

This function is used to verify if a link (pointed to by `path`) really exists (using the same method as the S_ISLNK macro defined in stat.h).

### Parameters

`path`

  Path to the link.

### Return Values

linkinfo() returns the `st_dev` field of the Unix C stat structure returned by the `lstat` system call. Returns a non-negative integer on success, -1 in case the link was not found, or `false` if an open.base_dir violation occurs.

### Examples

Example #1 linkinfo() example

`<?php
echo linkinfo('/vmlinuz'); // 835
?>`
