@deftypefun {void} {gnutls_tdb_set_store_commitment_func} (gnutls_tdb_t @var{tdb}, gnutls_tdb_store_commitment_func        @var{cstore})

@var{tdb}: The trust storage

@var{cstore}: The commitment storage function

This function will associate a commitment (hash) storage function with the

trust storage structure. The function is of the following form.

int gnutls_tdb_store_commitment_func(const char* db_name, const char* host,

const char* service, time_t expiration,

gnutls_digest_algorithm_t, const gnutls_datum_t* hash);

The  @code{db_name} should be used to pass any private data to this function.
