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);
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).
RETURN VALUE
On success, zero is returned. On error, -1 is returned and errno is set appropriately.ERRORS
- EINVAL
- No digest available (returned if SELABEL_OPT_DIGEST option not enabled).
- ENOMEM
- An attempt to allocate memory failed.
