gnutls_record_get_direction(3)

NAME
gnutls_record_get_direction - This function will 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.
