19 This function provides information about the internals of the record
20 protocol and is only useful if a prior gnutls function call (e.g.
21 gnutls_handshake()) was interrupted for some reason, that is, if a
22 function returned GNUTLS_E_INTERRUPTED or GNUTLS_E_AGAIN. In such a
23 case, you might want to call select() or poll() before calling the
24 interrupted gnutls function again. To tell you whether a file descrip‐
25 tor should be selected for either reading or writing,
26 gnutls_record_get_direction() returns 0 if the interrupted function was
27 trying to read data, and 1 if it was trying to write data.
