[gnutls-help] How to substitute gnutls_record_check_corked

[Heiko Schlittermann]

Hi,

Exim uses gnutls_record_cork() and …_uncork(). After uncorking I'd like
to wait until all data is flushed. Currently I do

  do {
    do outbytes = gnutls_record_uncork(state->session, 0);
    while (outbytes == GNUTLS_E_AGAIN);

     if (outbytes < 0)
       {
       ... /* return failure to the caller */
       return -1;
       }
  } while (gnutls_record_check_corked(state->session) > 0);


But GnuTLS < 3.2.8 does not have the gnutls_record_check_corked()
function. My naive attempt to define it according to that what I found
in the recent GnuTLS source failed, as it needs to access internal
data structures (I believe).

What is the proper way do wait until all data is flushed?

    Best regards from Dresden/Germany
