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 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.
