I’m working through a DLL hijacking exercise, and have a DLL written which works as expected when compiled in Visual Studio. Essentially, when the DLL is loaded, it executes a shell command and passes off legitimate functionality (in this example, the CheckEvenOdd and PrintAMessage functions) to the ori…

Setting GCServer = True when running on Linux in .net core project
How do set GCServer to true in a .net core project?

Preserve quotes when using wordexp
I’m trying to use the wordexp function to shell-like expansion on some strings. wordexp removes single and double quotes, I would like to preserve those however. My initial though was to just surround all quotation mark pairs in the input string with another pair of, this time escaped, quotation marks w…
Why does the free() function not return memory to the operating system?
When I use the top terminal program at Linux, I can’t see the result of free. My expectation is: free map and list. The memory usage that I can see at the top(Linux function) or /proc/meminfo get smaller than past. sleep is start. program exit. But The usage of memory only gets smaller when the program …
Does clang++ treat system headers in a more relaxed way?
The following struct is defined in the Linux system header file /usr/include/sys/inotify.h: Please note the last field name, which is a zero-length array. C++17 does not support zero-length array, so, if using struct inotify_event in a C++17 project and compiling it with -pedantic, a compiler warning should b…

How to link to Winsock when cross-compiling a Windows app on Linux?
I am porting a Cmake project from Linux to Windows. It uses sockets, so uses pthread in Linux and needs Winsock in Windows. The project is being compiled in Linux, using cross-compilation to create Windows binaries. The project is already compiling fine, and there is a switch to link pthreads when building fo…
