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.

        gnutls_pull_timeout_func is of the form, int
       (*gnutls_pull_timeout_func)(gnutls_transport_ptr_t, unsigned int ms);

       This callback is necessary when gnutls_handshake_set_timeout() or
       gnutls_record_set_timeout() are set. It will not be used when
       non-blocking sockets are in use. That is, this function will not operate
       when GNUTLS_NONBLOCK is specified in gnutls_init(), or a custom pull
       function is registered without updating the pull timeout function.

       The helper function gnutls_system_recv_timeout() is provided to simplify
       writing callbacks.
