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 SHA1 digest pointed to by digest, whose length  will  be
19       digest_len.   The list of specfiles used in the SHA1 digest calculation
20       is returned in specfiles with the number of entries in num_specfiles.
21
22       To  enable  selabel_digest()  to  return  this  information  the  SELA‐
23       BEL_OPT_DIGEST option must be enable in selabel_open(3).
24
25       The result of selabel_digest() must not be used after selabel_close(3).
