gnutls_record_set_max_size - API function
ssize_t gnutls_record_set_max_size(gnutls_session_t session,
- gnutls_session_t session
- is a gnutls_session_t type.
- size_t size
- is the new size
This function sets the maximum record packet size in this connection.
The requested record size does get in effect immediately only while sending
data. The receive part will take effect after a successful handshake.
Prior to 3.6.4, this function was implemented using a TLS extension called 'max
record size', which limits the acceptable values to 512(=2^9), 1024(=2^10),
2048(=2^11) and 4096(=2^12). Since 3.6.4, it uses another TLS extension called
'record size limit', which doesn't have the limitation, as long as the value
ranges between 512 and 16384. Note that not all TLS implementations use or
even understand those extension.
In TLS 1.3, the value is the length of plaintext content plus its padding,
excluding content type octet.
On success, GNUTLS_E_SUCCESS
(0) is returned, otherwise a negative error
code is returned.
