/*
Caching the data in a local buffer before sending it.
One can force the buffer to be flushed with 'net_flush'.
SYNOPSIS
net_write_buff()
net Network handler
packet Packet to send
len Length of packet
DESCRIPTION
Fill up net->buffer and send it to the client when full.
If the rest of the to-be-sent-packet is bigger than buffer,
send it in one big block (to avoid copying to internal buffer).
If not, copy the rest of the data to the buffer and return without
sending data.
NOTES
The cached buffer can be sent as it is with 'net_flush()'.
In this code we have to be careful to not send a packet longer than
MAX_PACKET_LENGTH to net_real_write() if we are using the compressed protocol
as we store the length of the compressed packet in 3 bytes.
RETURN
0 ok
1
