char ***specfiles, size_t *num_specfiles);

---

DESCRIPTIONselabel_digest() performs an operation on the handle hnd, returning the results of the SHA256 digest pointed to by digest, whose length will be digest_len.

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).

RETURN VALUEOn success, zero is returned. On error, −1 is returned and errno is set appropriately.
