NAME
       gnutls_record_send - API function

SYNOPSIS
       #include <gnutls/gnutls.h>

       ssize_t gnutls_record_send(gnutls_session_t session, const void * data,
       size_t data_size);

ARGUMENTS
       gnutls_session_t session
                   is a gnutls_session_t type.

       const void * data
                   contains the data to send

       size_t data_size
                   is the length of the data

DESCRIPTION
       This function has the similar semantics with send().  The only difference
       is that it accepts a GnuTLS session, and uses different error codes.
       Note that if the send buffer is full, send() will block this function.
       See the send() documentation for more information.

       You can replace the default push function which is send(), by using
       gnutls_transport_set_push_function().

       If the EINTR is returned by the internal push function then
       GNUTLS_E_INTERRUPTED will be returned. If GNUTLS_E_INTERRUPTED or
       GNUTLS_E_AGAIN is returned, you must call this function again, with the
       exact same parameters; alternatively you could provide a NULL pointer for
       data, and 0 for size. cf. gnutls_record_get_direction().

       Note that in DTLS this function will return the GNUTLS_E_LARGE_PACKET
       error code if the send data exceed the data MTU value - as returned by
       gnutls_dtls_get_data_mtu(). The errno value EMSGSIZE also maps to
       GNUTLS_E_LARGE_PACKET.  Note that since 3.2.13 this function can be
       called under cork in DTLS mode, and will refuse to send data over the MTU
       size by returning GNUTLS_E_LARGE_PACKET.

RETURNS
       The number of bytes sent, or a negative error code.  The number of bytes
       sent might be less than  data_size .  The maximum number of bytes this
       function can send in a single call depends on the negotiated maximum
       record size.
