This is my first message in this forum and I have a very short experience in C++.
This said, I would like to setup a server that accept strings from many clients, elaborates those strings and send them back to each client, in the correct way.
The elaboration is done through and external program, that I have to call with "execl", this is compulsory. So this program is a shared resource that should be "mutexed", in order to avoid wrong order in messages.
With a simple C syntax, I would like to so something like this:
Expand|Select|Wrap|Line Numbers
- //parent process
- while(1){
- int conn=accept(listen_sd,........);
- if( fork()==0 ){ //child process
- close(listen_sd);
- //reading from conn
- //elaborating received data, through a common resource, to be "mutexed"
- //sending results to conn
- }
- //parent process
- close(conn);
- }
Is there someone so kind and powerful who could help me in a practical and easy way?
(I am sorry but I'm using C++ only for 4 month and many things are still so hard)
Thank you all for your attention
