I am trying to write a simple client-server
processes in which
1) client accepts a string from a terminal
2) client sends a string to a server via a stream socket
3) server's child reads the string and sends back the
same string to the client via a similar socket.
4) client receives a string from a server and prints
to the screen.
All works fine, accept when I introduce an OOB msg
from client to server.
1) When client gets "OOB" string from the screen,
it sends MSG_OOB to the server with O character.
2) Server gets the SIGURG signal. However, the
recv(...,MSG_OOB) keeps on waiting for that
character.
I don't want NDELAY option on the socket.
Any idea what might be going wrong?
thanks in advance.
