Although the buffer overflow in our example causes the program to crash, this may not always be the case. For example, a buffer overflow may overwrite the return address in the stack. Therefore, the program jumps to the location specified by the new return address. This might lead to execut...
In C# I did:Expand table byte[] buffer = new byte[1024]; How to do it on C++?Thanks!All replies (3)Friday, July 25, 2008 6:47 PM ✅Answeredunsigned char buffer[1024]; // automatic/stack-based variableunsigned char *buffer = new unsigned char[1024]; // allocated on the h...
outBuffer.Length + 2; } } Robust ProgrammingThe client and server processes in this example are intended to run on the same computer, so the server name provided to the NamedPipeClientStream object is ".". If the client and server processes were on separate computers, "." would be repl...

Here's the reason. When you first start the copy operation, the copy buffer is empty. Therefore, there is plenty of room in the buffer to move the files into. But the buffer then fills up, because the files don't move out of the buffer as fast as they are moving in. ...
TheCryptHashDatafunction is used to compute the cryptographic hash of some supplied data. This function can be called multiple times to compute the hash on large data or different pieces of data. As an example, we will hash the data that is contained in a buffer pointed to bypBufferand that...
If you do manage to force the compiler to do it, this will actually end up with a runtime error: So the only way to get this to work without an error is to allocate 4 bytes of memory. This is where Pavel's solution come in. ...
Okay, it wastes a slot to distinguish between full and empty; however this isn't a safety issue. And it looks just as careful as the other side. It looks like this queue was coded very carefully. There are no clear buffer overflows. On x86 in fact, it's pretty much correct1---if...
I think, however, there hasn't been a truly in-depth cheatsheet which describe a variety of configurations and important cross-cutting topics for HTTP servers. That's why I created this repository to help us to configure high performing NGINX web and proxy servers that are fast, secure and ...
