selabel_digest(3)

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);</code></pre>
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.
