 link_name

    The name of the symbolic link to be deleted.

2 - Description

    The unlink function deletes the specified symbolic link (link_
    name) from the system. The contents of the symbolic link are not
    examined, and no action is performed on the file specified in the
    contents. For other files, the unlink function behaves the same
    as the C RTL remove function.

                       value from remove.
