selabel_digest - Return digest of specfiles and list of files used
#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);
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).
On success, zero is returned. On error, -1 is returned and errno is set appropriately.
EINVAL No digest available (returned if SELABEL_OPT_DIGEST option not enabled). ENOMEM An attempt to allocate memory failed.
