Function
GLibfile_read_link
since: 2.4
Description
Reads the contents of the symbolic link filename
like the POSIX
readlink()
function.
The returned string is in the encoding used for filenames. Use
g_filename_to_utf8()
to convert it to UTF-8.
The returned string may also be a relative path. Use g_build_filename()
to convert it to an absolute path:
g_autoptr(GError) local_error = NULL;
g_autofree gchar *link_target = g_file_read_link ("/etc/localtime", &local_error);
if (local_error != NULL)
g_error ("Error reading link: %s", local_error->message);
if (!g_path_is_absolute (link_target))
{
g_autofree gchar *absolute_link_target = g_build_filename ("/etc", link_target, NULL);
g_free (link_target);
link_target = g_steal_pointer (&absolute_link_target);
}
