NAME         top

       gnutls_record_set_max_size - API function

SYNOPSIS         top

       #include <gnutls/gnutls.h>

       ssize_t gnutls_record_set_max_size(gnutls_session_t session,
       size_t size);

ARGUMENTS         top

       gnutls_session_t session
                   is a gnutls_session_t type.

       size_t size is the new size

DESCRIPTION         top

       This function sets the maximum amount of plaintext sent and
       received in a record in this connection.

       Prior to 3.6.4, this function was implemented using a TLS
       extension called 'max fragment length', which limits the
       acceptable values to 512(=2^9), 1024(=2^10), 2048(=2^11) and

       Since 3.6.4, the limit is also negotiated through a new TLS
       extension called 'record size limit', which doesn't have the
       limitation, as long as the value ranges between 512 and 16384.
       Note that while the 'record size limit' extension is preferred,
       not all TLS implementations use or even understand the extension.

DEPRECATED         top

       if the client can assume that the 'record size limit' extension
       is supported by the server, we recommend using
       gnutls_record_set_max_recv_size() instead.

RETURNS         top

       On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a
       negative error code is returned.
