NAME
selabel_digest - Return digest of specfiles and list of files used
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 SELA-
BEL_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.
