gnutls_transpor...imeout_function(3) gnutls gnutls_transpor...imeout_function(3) NAME gnutls_transport_set_pull_timeout_function - API function SYNOPSIS #include <gnutls/gnutls.h> void gnutls_transport_set_pull_timeout_function(gnutls_session_t session, gnutls_pull_timeout_func func); ARGUMENTS gnutls_session_t session is a gnutls_session_t type. gnutls_pull_timeout_func func a callback function DESCRIPTION This is the function where you set a function for gnutls to know whether data are ready to be received. It should wait for data a given time frame in milliseconds. The callback should return 0 on timeout, a positive number if data can be received, and -1 on error. You'll need to override this function if select() is not suitable for the provided transport calls. As with select(), if the timeout value is zero the callback should return zero if no data are immediately available. The special value GNUTLS_INDEFI- NITE_TIMEOUT indicates that the callback should wait indefinitely for data. gnutls_pull_timeout_func is of the form, int (*gnutls_pull_time- out_func)(gnutls_transport_ptr_t, unsigned int ms); This callback is necessary when gnutls_handshake_set_timeout() or gnutls_record_set_timeout() are set, under TLS1.3 and for enforcing the DTLS mode timeouts when in blocking mode. For compatibility with future GnuTLS versions this callback must be set when a custom pull function is registered. The callback will not be used when the session is in TLS mode with non-blocking sockets. That is, when GNUTLS_NONBLOCK is specified for a TLS session in gnutls_init(). The helper function gnutls_system_recv_timeout() is provided to simplify writing callbacks. SINCE 3.0 REPORTING BUGS Report bugs to <bugs@gnutls.org>.
