I am writing a socket ...
When I call accept function, it keeps on waiting for the new connection.
I want to know, can I call accept function in some manner so that it doesn't completely hang the execution. I don't want to use Ctrl+C to exit the server everytime.
I know threading is an option, but some other better option?
Use non-block.
You set non-block like this:Originally Posted by GNU C Manual
Code:#include <fcntl.h> fcntl(socket_fd,F_SETFL,O_NONBLOCK);
C programming resources:
GNU C Function and Macro Index -- glibc reference manual
The C Book -- nice online learner guide
Current ISO draft standard
CCAN -- new CPAN like open source library repository
3 (different) GNU debugger tutorials: #1 -- #2 -- #3
cpwiki -- our wiki on sourceforge
Google for "non-blocking socket". You should find a lot of examples about it. I had the same doubt.

Try using select() on it. Configure an internal pipe that you can use to break out of the select wait state (if you need to break out for some reason --- like your main tread is exiting)
