fsockopen() returns null pointer, and $errstr is empty (no error message)
[Edit] I have reedited the previous question - since I had misunderstood what was causing the problem - and therefore the ample snippet I had before was a red herring. Thanks to wimdvx, I have a clearer idea as to what is going on. First of all, I am using code that is base on this one, to handle IPN notifications from Paypal. I was u...

Start a process in the background in Linux with C

Retrieve plain text script from compiled bash script
Some time ago, i wrote some bash scripts for my school. I thought it would be very clever to 'protect' them, so i compiled them with shc into a binary file.

On Linux, why does the destructor run twice on shared instance of global variable in C++?
On Linux I have some generated C++ code from a static library that defines a global variable. A single instance of this global variable is shared between two shared libraries that refer to its symbol. When the process shuts down and the static termination phase is run, I see that the destructor on this shared instance is run twice! Pr...

How can I spy on communication between a process and a terminal?
