NAME
gnutls_record_get_direction - return the direction of the last
interrupted 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
descriptor 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.
