gnutls_record_set_max_size(3) gnutls gnutls_record_set_max_size(3)
gnutls_record_set_max_size - API function
#include <gnutls/gnutls.h>
ssize_t gnutls_record_set_max_size(gnutls_session_t session,
size_t size);
gnutls_session_t session
is a gnutls_session_t type.
size_t size is the new size
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
4096(=2^12).
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.
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.
On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative
error code is returned.
