Hi all
why
value("{1,") gives GET_EOF, but
value("{1") gives GET_FAIL ?
I'm writing chat program. The exchange of messages could be done with =
sequences :
client will send something like {myname,message,other_info}. The server =
will read buffer and then decide :
GET_SUCCES =3D> process message
GET_FAIL =3D> error, ignore this message, send warning to client
GET_EOF =3D> whole message not sended yet, read the buffer again
Should I use some special char after the end of sequence ?
Thanks
