I'm currently writing up some CPPunit tests for a program that tests a hardware communication port (yes, I'm writing unit tests for a tester app ;-) ). One of the classes I'm testing is basically a wrapper around the device's file descriptor; I make read() and write() calls on the file descriptor. Is there a device file/driver on Linux...
I need to print the content of a fifo (named pipe) to standard output. I could use the command: cat fifo The problem is that cat doesn't return.

The full error message is: \machi...

Hi: I have a Symbol LS2208 barcode scanner and works OK in my linux box (Kubuntu 8.10 Intrepid Ibex).

Write over or create the datafile. I will put the script in /etc/cron.hourly/ on Ubuntu which will make it execute once each hour. What would a good place to store t...

I need to write a small socket server proxy application that accepts connections from local applications on ALL interfaces (socket should bind to 0.0.0.0). I'm not aware of way to achieve this (I have additional requirements that prevent binding to the 127.0.0.1). A first attempt at this does the following: bind(0.0.0.0) ... s = accep...
I've been reading its man page but haven't yet been successful in figuring out how it works. On calling system(), is a new child process forked and the shell binary exec()-ed in it? That may be a stupid guess though. ...
Hi. I´m pretty new to programming in C++ and I´m using pthreads. I´m cross compiling my code for OpenWRT but for some reason I get segmentation fault when I run the program on my board but it runs fine on my PC. I suspect that the error occurs in the linking stage of the compilation because I tried a small C program and that worked fine...
