Convert Program to Shared Library

[Andy202]

I have a program that sends and receives data via a TCP/IP socket, but I would like to convert this application to a Shared Library so that other programs can use this library to send() and receive() data.

This is on a Unix platform using a gcc compiler.

Forgetting about the send option for the present, I have the typically:-

// The client program for the application.
#include "initComms.h"
 
int main (int argc, char **argv)
{
   // This is the main driver program for the Client.
 
   static DataStruct     dData;
   InitComms();
 
   printf("******** Into Client Main Loop    ********\n");
   while(true)
   {
    ACE_TRY
    dData = getData();
    usleep(2000);
   }
   return 0;
}

So my question is what type of Shared Libray would I convert to (Static or Dynamic) and how would you make the getData() available to the calling program.

Many thanks,

Andy.
