linkinfo

Gets information about a link

&reftitle.description; ``int``false```linkinfo` `string` `path`

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`).

&reftitle.parameters;

`path`

- Path to the link.

&reftitle.returnvalues;

`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.
