Want to know the logic behind send() & recv() call

chansanle · 12-25-2011, 08:19 AM

I was just learning about the socket programming and came across send and recv() call which is been performing the same task of read and write() except few functionality. So i was eager to know abt "how the contents of the buffer have been written to the network" and "how it is retrieved from the network and written to the buffer".

Thanks in Advance,

That's what manual is good for.

Thanx Nevemteve for ur reply, but in the manual they wil have the info regarding the arg/parametres and their datatypes. But i need a technical info. or how they have implemented. So may i get any links for tat

You mean you are interested in technical details of networking?
For start:

http://en.wikipedia.org/wiki/Internet_Protocol

Thanx for the links NevemTeve. But for me i need some technical details abt programming i.e. i want it in a programmers perspective of approach to implement that send and recv()

Pick one:
1. You want to write kernel-code to implement send(2) and recv(2).
2. You want to use send(2) and recv(2) in your program.

You knowledge is insufficient yet for that. For a start, read the books of Andrew S. Tanenbaum.
