gnutls_record_get_direction(3)	    gnutls	gnutls_record_get_direction(3)

NAME
       gnutls_record_get_direction  -  return the direction of the last inter‐
       rupted function call

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.
