NAME
       gnutls_record_get_direction - API function

SYNOPSIS
       #include <gnutls/gnutls.h>

       int gnutls_record_get_direction(gnutls_session_t session);

ARGUMENTS
       gnutls_session_t session
		   is a gnutls_session_t structure.

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

RETURNS
       0 if trying to read data, 1 if trying to write data.
