global variable i;
SIGCHLD handler function()
{
i--;
}
handle()
{
fork() --> FORK2
}
main()
{
while(1)
{
if(i<5)

I just came to realize that my system is not limiting the amount of processes per user properly thus not preventing a user from dring a fork-bomb and crashing the entire system:
user@thebe:~$ cat /etc/security/limits.conf | grep user
user hard nproc 512
user@thebe:~$ ulimit -u
1024

I'm using fork() on PERL in windows (activeperl) for a basic socket server, but apparently there are problems (it won't accept connections after a few times), is there any workaround?

When reading about pipes in Advanced Programming in the UNIX Environment, I noticed that after a fork that the parent can close() the read end of a pipe and it doesn't close the read end for the child. When a process forks, does its file descriptors get retained? What I mean by this is that before…

I know that fork() returns differently for the son and father processes, but I'm unable to find information on how this happens. How does the son process receive the return value 0 from fork? And what is the difference in regards to the call stack? As I understand it, for the father it goes something…

Our app runs in jvm 32 bit, even when in windows x64. Now, at some point, I need to access some registry values, for example HKEY_LOCAL_MACHINE/SOFTWARE/mycomp.
I do this by executing
cmd /C reg query HKEY_LOCAL_MACHINE\SOFTWARE\mycop
from Runtime.exec() and parsing the output. This works fine…

Basically in a nutshell is I am using exec() to run WinSCP, which is causing the script to hold until the file is uploaded. Is there anyway to make it so that the script continues, and the upload runs in the background?

Hey, I'm trying to execute a program on windows through PHP, the command is posted below. This doesn't seem to be running through the script at all, even though it works when the command is manually entered into the command prompt.
