Синопсис (Synopsis)
#include <selinux/selinux.h>
       #include <selinux/label.h>
       int selabel_digest(struct selabel_handle *hnd,
                          unsigned char **digest, size_t *digest_len,
                          char ***specfiles, size_t *num_specfiles);
Описание (Description)
selabel_digest() performs an operation on the handle hnd,
       returning the results of the SHA1 digest pointed to by digest,
       whose length will be digest_len.  The list of specfiles used in
       the SHA1 digest calculation is returned in specfiles with the
       number of entries in num_specfiles.
       To enable selabel_digest() to return this information the
       SELABEL_OPT_DIGEST option must be enable in selabel_open(3).
       The result of selabel_digest() must not be used after
       selabel_close(3).
Возвращаемое значение (Return value)
On success, zero is returned.  On error, -1 is returned and errno
       is set appropriately.
Ошибки (Error)
EINVAL No digest available (returned if SELABEL_OPT_DIGEST option
              not enabled).
       ENOMEM An attempt to allocate memory failed.
