NAME

6       gnutls_record_get_direction - API function
7

SYNOPSIS

9       #include <gnutls/gnutls.h>
10
11       int gnutls_record_get_direction(gnutls_session_t session);
12

ARGUMENTS

14       gnutls_session_t session
15                   is a gnutls_session_t structure.
16

DESCRIPTION

18       This  function  provides  information about the internals of the record
19       protocol and is only useful if  a  prior  gnutls  function  call  (e.g.
20       gnutls_handshake())  was  interrupted  for  some  reason, that is, if a
21       function returned GNUTLS_E_INTERRUPTED or GNUTLS_E_AGAIN.   In  such  a
22       case,  you  might  want  to  call select() or poll() before calling the
23       interrupted gnutls function again.  To tell you whether a file descrip‐
24       tor    should    be   selected   for   either   reading   or   writing,
25       gnutls_record_get_direction() returns 0 if the interrupted function was
26       trying to read data, and 1 if it was trying to write data.
27
28       This function's output is unreliable if you are using the
29        session in different threads, for sending and receiving.
30

RETURNS

32       0 if trying to read data, 1 if trying to write data.
