selabel_digest(3) SELinux API documentation selabel_digest(3)

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 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.
