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.
