Actually, I think TEMP_FAILURE_RETRY does it for me.
Still, I am stuck. I tried few small modifications and still I get SIGPIPE only during second communication trial.
Timeout on select does not...

I understand. So how to discover server breakdown on the first request sending?

Yes! That's it. The problem was that there appeared SIGPIPE during second communicate() invocation. It was killing the program (SIGPIPE default action is to terminate process).
But there is still...

Getting rid of ERR does not help, because this if ((send...) < 0) condition is never fulfilled. It looks like send() kills program. It sounds crazy.
I have put my whole code on github:...

I put some info printing to my code in order to examine where function execution breaks. Now it lookes like that:/***

* Returns:
* 0 success

ERR() already does it.
#define ERR(source) (fprintf(stderr,"%s:%d\n",__FILE__,__LINE__),\
perror(source),kill(0,SIGKILL),\
exit(EXIT_FAILURE))It is...

I have tried <=, does not help.
I have also tried removing TEMP_FAILURE_RETRY, nothing changes.
More strange is fact, that when I execute this first time on the client side (of course during server...

I have already written a function which aim is to send some data (request) and then receive some data (response) from the server.

As Corona688 said, it is already passed as reference in my case. I should have checked this more carefully before posting.

Thank you for your help :)

First, let me show my code to explain what i am going to do:
I have function:void initialize_board(char...

Hi.
I am writing client - server application using TCP sockets.
I need some very basic functionality, namely: how to check if another "participant" of the connection is still present?
I want to...

I read on stackoverflow.com that it is more portable. I have no particular must, just curiosity, I am also reading about POSIX ones.Oh, I haven't noticed that fact. Good to know.Ok, I will remember...

Thanks! Now I think that would give me some kickoff. I'll be back if any question arises.

You are right, I have not told too much.
First I would like to say that this is only my startup program, which may or may not grow into something more clever ;) I am familiar with object oriented...

Hi.
I am just making first steps in Linux POSIX programming. I have read some tutorials on processes, signals and sockets (thanks Beej!), so some basic knowledge I have already got.
I want to write...
