| Hi there,
I am doing some programming on sockets and I would like an introduction to
sending files through unicast sockets. I later will be making a program
that's a server and client that will allow people to search files on some
directory on my computer and get them if they are available. kinda like p2p
applications.
The idea is having a bunch of people connecting to the same multicast
network. a user would send a query looking for a filename. if the file is
found the owner would send him the requester the ip and port in order to
open a unicast connection to the owner. i have coded some parts of the
program but i dont know how to send a file. any help would be very
appreciated.

Use a TCP connection and sendfile().

Not too hard, just do something like:
- open() the file
- read() a block of data from the file into a char buffer
- sendto() to the data from the char buffer
- continue until the file read() returns EOF
- close() file
Cheers,
