Can anyone plz me. I need a sample code for the following description.  
Its urgent.

It is C/Socket program with the following descriptions:  
NAME  
coreadServer - Concurrent Readers Server.  
coreadClient - Concurrent Readers Client.  
SYNOPSIS  
coreadServer \<OutputFile\>  
coreadClient \<n\> \<InputFile\> \<RemoteHost\> \<Port\>  
DESCRIPTION  
� The coreadClient program creates n children processes communicating with the parent using udp sockets.  
v Each process i, i= 1, 2,.., n do the following:  
Sleeps a random amount of time T, where T \<= n seconds and when it wakes up it:  
� Reads 128 characters from InputFile & terminates if there is no more data to read.  
� Use the udp socket to send the PID followed by the data that have been read.  
v The parent reads from its udp socket and sends the received packets to the coreadServer using its tcp socket.  
� The coreadServer program displays its port number, reads from its tcp socket and produces two files:  
� The OutputFile should be identical to the InputFile and  
� The PIDCounts contains the number of reads performed by each child process.

Example:  
% coreadServer OutputFile  
coreadServer Port#: 61634  
running at host: xx.xx.xx.edu (128.81.4.116 )  
acceped coreadClient connection  
from: 128.82.4.116:61643 (xx.xx.xx.edu)  
% coreadClient 20 InputFile ra 61634  
% cat PIDReport

Sounds like homework. That's against the rules. Locking the thread.
