I saw users of this forums saying that the way to shared sockets is using UNIX Sockets, but this is the only way in my scenario?

My Scenario:

I have a process that is the server. Server accepts clients (sockets) and then call to fork. If two clients connects to my server, parent process will have two childs, and now is my problem, one of this child need to send a message to the another child.

First, I thinked that I could save fd socket in share memory, and then using this fd in another child I'll be able to send messages to another client, but doesn't works...

Any ideas?? Thanks!

PD: Sorry for my bad english

Hi,

you can use shared_memory IPC to share the sockets(any data) between the two processes via a unique key. Otherwise you can instead create threads when you serve a new request. Then you save the overhead of forking a new process.

Thanks,
Gaurav.

CLP(1)							      General Commands Manual							    CLP(1)

NAME

       clp - linear program solver

SYNOPSIS

       clp filename [ options ] solutionfile

DESCRIPTION

       This manual page documents briefly the clp command.

       clp -- interface to the coin linear programming solver. clp solves the following linear optimization program:

	   minimize	 c^t x
	   such that:	 row_lb <= Ax <= row_ub
			 column_lb <= x <= column_ub

OPTIONS

       When  no options are given clp enters the interactive command line mode.  Otherwise the program enters a batch mode, for which a summary of
       options is included below.  For a complete description, see /usr/share/doc/coinor-libclp-doc.

       -help  Show summary of options.

       -primalsimplex
	      solve the problem using the primal simplex method

       -dualsimplex
	      solve the problem using the dual simplex method

       -maximize
	      maximize the problem

SEE ALSO

       glpsol(1),dsdp5(1)

       This program is fully documented in the accompanying html documentation which can  be  found  in  /usr/share/doc/coinor-libclp-doc  if  the
       coinor-libclp-doc package is installed.
