Explanation: It simply creates a single new thread, so as to check the thread stack size and NOT the program stack size, in case they differ, then it has that thread repeatedly allocate 128 bytes of memory on the stack (NOT the heap), using the Linux alloca() call, after which it wr...
In C printf(), %n is a special format specifier which instead of printing something causes printf() to load the variable pointed by the corresponding argument with a value equal to the number of characters that have been printed by printf() before the occurrence of %n. filter_none edit pl...

construction. Thecatchhandler is executed and the program resumes execution after the last handler—that is, at the first statement or construct that is not acatchhandler. Control can only enter acatchhandler through a thrown exception, never through agotostatement or acaselabel in aswitch...
When I am trying to compile a particular program with -Wall, GCC is showing the warning as: expcal.c:66:5: warning: statement with no effect [-Wunused-value] this warning is referring the line: ed.operator[j] == str[i]; which is found in the following loop: for(i=0;i<...
This article is targeted toward anyone interested in building a profiler to examine managed applications. I will describe how you can program your profiler to walk managed stacks in the common language runtime (CLR) of the .NET Framework. I'll try to keep the mood light, because the topic ...
What's lost in the stack allocation discussion is that higher level program structure changes will often have much better performance results. Low level optimizations are typically done last in the development cycle and require the use of a code instruction level profiler. It would help if the...
If you are creating any kind of computer service—that is, a computer program that can receive multiple requests from multiple sources for some task to be completed—then part of the challenge of creating the service is deciding the order in which the incoming requests will be handled. The tw...

By doing zero initialization, a pointer that is not correctly initialized might end up just going down the “NULL pointer” branch that a program has. This results in a program that doesn’t crash but might not be giving you the results you want. If you initialize a pointer to a garbage...
