@deftypefun {int} {gnutls_store_commitment} (const char * @var{db_name}, gnutls_tdb_t @var{tdb}, const char * @var{host}, const char * @var{service}, gnutls_digest_algorithm_t @var{hash_algo}, const gnutls_datum_t * @var{hash}, time_t @var{expiration}, unsigned int @var{flags})
@var{db_name}: A file specifying the stored keys (use NULL for the default)

@var{tdb}: A storage structure or NULL to use the default

@var{host}: The peer's name

@var{service}: non-NULL if this key is specific to a service (e.g. http)

@var{hash_algo}: The hash algorithm type

@var{hash}: The raw hash

@var{expiration}: The expiration time (use 0 to disable expiration)

@var{flags}: should be 0 or @code{GNUTLS_SCOMMIT_FLAG_ALLOW_BROKEN} .

This function will store the provided hash commitment to
the list of stored public keys. The key with the given
hash will be considered valid until the provided expiration time.

The  @code{tdb} variable if non-null specifies a custom backend for
the storage of entries. If it is NULL then the
default file backend will be used.

Note that this function is not thread safe with the default backend.

@strong{Returns:} On success, @code{GNUTLS_E_SUCCESS}  (0) is returned, otherwise a
negative error value.

@strong{Since:} 3.0
