15 gnutls_session_t session
16 is a gnutls_session_t type.

18 size_t size is the new size

21 This function sets the maximum amount of plaintext sent and received in
22 a record in this connection.
23
24 Prior to 3.6.4, this function was implemented using a TLS extension
25 called 'max fragment length', which limits the acceptable values to
26 512(=2^9), 1024(=2^10), 2048(=2^11) and 4096(=2^12).
27
28 Since 3.6.4, the limit is also negotiated through a new TLS extension
29 called 'record size limit', which doesn't have the limitation, as long
30 as the value ranges between 512 and 16384. Note that while the 'record
31 size limit' extension is preferred, not all TLS implementations use or
32 even understand the extension.
33
35 if the client can assume that the 'record size limit' extension is sup‐
36 ported by the server, we recommend using
37 gnutls_record_set_max_recv_size() instead.

40 On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative er‐
41 ror code is returned.
