Process communication

[sjaiswal]

What would be the best way of process communication in one to many model. i.e one process is talking to many process.

This one process should know from which process the reply has come.
Communication would be two way. A-->pn and pn-->A

|-------p1

|-------p2

|-------p3

|-------p4

process A----.

.

.

|-------pn-3

|-------pn-2

|-------pn-1

|-------pn

using sockets will be the best solution for this.......

[sjaiswal]

How can i create local sockets . I can't find good reference on this.
Somebody having an idea??

[robinsonvpanicker]

go through the man pages....but since u r a beginner do use steven richards book on socket programming which will help u immenselyy and also mastering socket programming.......or the next easiest way is google for some socket programming tutorials which will be definitely available......

I believe that robinsonvpanicker is referring to the book published by Addison Wesley entitled UNIX Network Programming, volume one, by W. Richard Stevens of happy memory, Bill Fenner, and Andrew M. Rudoff. If you're going to do serious network programming, this book is indispensable.

If process A wishes to broadcast to every process in a particular set, and the total amount of broadcast data is neither infinite nor extremely huge, another alternative is for process A to create a file and repeatedly append to it. In that case, the other processes can check the length of the file repeatedly to see whether that length has changed.

This alternative is more crude than the network programming approach, but if it works for you it will probably take much less development time, particularly if you're not already familiar with network programming and have no other reason to become familiar with it.

If you use this alternative, be sure to use advisory record locking to synchronize activity within the file.
