DESCRIPTION
This function sets the maximum record packet size in this connection. This property can only be set to clients. The server may choose not to accept the requested size. 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.

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