Problem with connect()


Hi

I am trying to write a simple client server socket program in C using Internet Domain Sockets.
The connect call is failing with the error message- Bad File Descriptor.
The server program is running fine(I think). Can someone help me out with this.
I am logged in as root when executing the programs.

It sounds like you didn't check the return value of the socket() call - or that you never even called socket().

To connect:
1. open a socket: socket()
2. fill in an address struct with the destination address (IP and port)
3. make the connection: connect()

The socket has to be a stream type; if it is a 'datagram' then connect will fail since connect() only works with streams - which makes sense because a datagram like UDP is a "connectionless" protocol.

hey
Thanks for the help. Unfortunately i deleted the file in frustration, rewrote it and somehow it started working. Now i can't remember what was wrong with it.
