NAME

       selabel_lookup - obtain SELinux security context from a string label

SYNOPSIS

       #include <selinux/selinux.h>
       #include <selinux/label.h>

       int selabel_lookup(struct selabel_handle *hnd,
                          char **context,
                          const char *key, int type);

       int selabel_lookup_raw(struct selabel_handle *hnd,
                              char **context,
                              const char *key, int type);

DESCRIPTION

       selabel_lookup()  performs  a  lookup operation on the handle hnd, returning the result in
       the memory pointed to by context, which must be freed by the caller using freecon(3).  The
       key  and  type  parameters  are  the  inputs  to  the lookup operation and are interpreted
       according to the specific backend that handle is open on.

       selabel_lookup_raw() behaves identically to selabel_lookup() but does not perform  context
       translation.

RETURN VALUE

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

ERRORS

       ENOENT No context corresponding to the input key and type was found.

       EINVAL The  key  and/or  type  inputs  are  invalid,  or the context being returned failed
              validation.

       ENOMEM An attempt to allocate memory failed.
