NAME

SYNOPSIS

9       #include <selinux/selinux.h>
10       #include <selinux/label.h>
11
12       int selabel_lookup(struct selabel_handle *hnd,
13                          char **context,
14                          const char *key, int type);
15
16       int selabel_lookup_raw(struct selabel_handle *hnd,
17                              char **context,
18                              const char *key, int type);

DESCRIPTION

21       selabel_lookup() performs a lookup operation on the handle hnd, return‐
22       ing the result in the memory pointed to by context, which must be freed
23       by  the  caller  using freecon(3).  The key and type parameters are the
24       inputs to the lookup operation and are  interpreted  according  to  the
25       specific backend that handle is open on.
26
27       selabel_lookup_raw()  behaves  identically to selabel_lookup() but does
28       not perform context translation.

RETURN VALUE

31       On success, zero is returned.  On error, -1 is returned  and  errno  is
32       set appropriately.
33

ERRORS

35       ENOENT No context corresponding to the input key and type was found.
36
37       EINVAL The  key  and/or  type  inputs are invalid, or the context being
38              returned failed validation.
39
40       ENOMEM An attempt to allocate memory failed.
