A set of functions is provided and their purpose is to load -to \gnutls{} the required callbacks to access the transport layer. - -\begin{itemize} -\item \printfunc{gnutls_transport_set_push_function}{gnutls\_transport\_set\_push\_function} -\item \printfunc{gnutls_transport_set_pull_function}{gnutls\_transport\_set\_pull\_function} -\item \printfunc{gnutls_transport_set_ptr}{gnutls\_transport\_set\_ptr} -\end{itemize} - -These functions accept a callback function as a parameter. -The callback functions should return the number of bytes written, or -1 on -error and should set errno appropriately. -\par -\gnutls{} currently only interprets the EINTR and EAGAIN errno values and -returns the corresponding \gnutls{} error codes GNUTLS\_E\_INTERRUPTED and -GNUTLS\_E\_AGAIN. -These values are usually returned by interrupted system calls, or -when non blocking IO is used. All \gnutls{} functions -can be resumed (called again), if any of these error codes is returned. -The error codes above refer to the system call, not the \gnutls{} function, -since signals do not interrupt \gnutls{}' functions. - -\par -By default, if the transport functions are not set, \gnutls{} will use -the Berkeley Sockets functions. In this case -\gnutls{} will use some hacks in order for \emph{select()} to work, thus -making it easy to add \tls{} support to existing TCP/IP servers. |
