7

SYNOPSIS

9       #include <selinux/selinux.h>
10       #include <selinux/label.h>
11
12       int selabel_digest(struct selabel_handle *hnd,
13                          unsigned char **digest, size_t *digest_len,
14                          char ***specfiles, size_t *num_specfiles);

DESCRIPTION

17       selabel_digest() performs an operation on the handle hnd, returning the
18       results of the SHA256 digest pointed to by digest, whose length will be
19       digest_len.   The  list of specfiles used in the SHA256 digest calcula‐
20       tion is returned in specfiles with the number of entries  in  num_spec‐
21       files.
22
23       To  enable  selabel_digest()  to  return  this  information  the  SELA‐
24       BEL_OPT_DIGEST option must be enable in selabel_open(3).
25
26       The result of selabel_digest() must not be used after selabel_close(3).

RETURN VALUE

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

ERRORS

33       EINVAL No  digest  available (returned if SELABEL_OPT_DIGEST option not
34              enabled).
