gnutls_record_get_direction — return the direction of the last interrupted function call
#include <gnutls/gnutls.h>
int
gnutls_record_get_direction( |
gnutls_session_t | session); |
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.
The full documentation for gnutls is maintained as a Texinfo manual. If the info and gnutls programs are properly installed at your site, the command
info gnutls
should give you access to the complete manual.
