Hi, EDIT: Thanks for the answers so far, at least I can compile it now, but I still get a segmentation error. For compilation I use the following line: gcc -g -O0 -I../include -L../ test.c -static -lrt Source Code is as follows: #include <sys/time.h> #include <time.h> #include <stdio.h> struct timespec *diff(struct timespec *start...
I have done the following: Create a virtual timer that triggers repeatedly. Install signal handler for SIGVTALRM Call clone syscall Set sched_affinity such that the cloned thread runs on a different CPU Will the cloned thread also be listening for SIGVTALRM? So will both the threads call the signal handler when SIGVTALRM is triggered...

So, I think I'm going to do some coding on Linux soon, but so far the biggest turn-off for me was that I'm very reluctant to move away from my current text/code editor. I'm looking for a Linux text/code editor (either GUI or text-based) which is (or can be configured to be) as close as possible to my current setup of FAR Manager's built-...

I would like to know how to create console applications with better control of input and output using C. For example, how does the text-editor nano display the file contents in a certain portion of the screen and then keep a list of commands stationary on the bottom.

I am trying to setup cruisecontrol in a Linux environment. I have some experience with cc.NET, but this is the first time I have ever tried to use the 'nix version. This is what I have for my build.xml: When I run "ant project1", everything seems to work except that it tells me: /opt/cruisecontrol-bin-2.8.3/projects/portal/build.xml:...

Hello. I'm using SuSE 11.2. It has GCC 4.4 installed by default. I've downloaded and built from sources GCC 4.3.4 while leaving 4.4 as well. I've also altered environment variables - CC, CPP, CXX and PATH - to point to GCC 4.3 binaries. And when I run Android 1.5 make, I get following error: make: * No rule to make target ../../../../bi...

I am trying to use "strace -p" to attach to an already running JBoss process. JBoss is using the 1.5.0_15 Java JDK. Unfortunately, this doesn't work - I only get a single futex() result: # strace -p 3388 Process 3388 attached - interrupt to quit [ Process PID=3388 runs in 32 bit mode. ] futex(0x8f18f7c, FUTEX_WAIT_PRIVATE, 1, NULL <unfi...
I need to double-fork vmware so it doesn't inherit the terminal ID (TTY/pts). This is what I have so far, but I can't get access to the runtime.exec process to fork another process (which removes the terminal ID). Runtime runtime = Runtime.getRuntime(); Process proc = runtime.exec("vmware"); Is there a way to "daemonize" in Java? ...
