LibSerial and signal_handler

[roxlu]

Hi all

I'm using LibSerial
(http://libserial.sourceforge.net/mediawiki/index.php/LibSerial_Tutorial)
for communication with my serial port. I can read and write data. But,
as I've implemented it as a part of a tcp/ip server, I need to use the
signal_handler functionality. Actually I want a function to be called
whenever data arrives at the serial port. But I'm still learning c++
and I really can't figure out how to do this.

Here is a class list:
http://libserial.sourceforge.net/doxygen/annotated.html with a
PosixSignalDispatcher, which I think is needed in my case, but how can
I 'use' this with a SerialStream object?

Thanks in advance,
Greetngs roxlu

I'm sorry, but your question is totally off-topic here. I suggest you
use the SourceForge forum for your project, as people who know that
library hang out there.

Here, we are discussing the language C++ as defined by the standard
(either ISO/IEC 14882:2003 or ISO/IEC 14882:1998(E)).

Oke thanx, but the SF forums for this library aren't used, so I hoped
someone here could help me...

Hi,

Use the "select" call. See the manual pages (man select).

Signals and signal handling are part of the C and C++ Standards. The
