That sort of overflow can be avoided if the program includes sufficient bounds checking to flag or discard data when too much is sent to a memory buffer. Buffer overflows are among the most persistent and dangerousvulnerabilities in software, often exploited by attackers to gain unauthorized access...
That is a program bug and should be avoided (such as by sanitizing input with an if statement like Marcus demonstrated).If you need, for some reason, to catch Win32 exceptions, such as access violations and divide by zero errors (normally only recommended if you plan to log the error ...
How can this allocation for synchronous completions be avoided more generally in situations where the performance overhead really matters?That’s where ValueTask<TResult> comes into the picture (a much more detailed examination of ValueTask<TResult> is also available). ValueTask<TResult> started ...
Of course, locks are still used internally when allocating or freeing from a region (since a malloc from one thread can still be freed in a different thread) but the chance of two threads contesting a lock is significantly reduced. The likelihood of cache lines shared unnecessarily between CPUs...
If we pass to this function, not an array, we get a compilation error. In C ++17 you can use std::size.In C++11, the function std::extent was added, but it isn't suitable as countof, because it returns 0 for inappropriate types. ...
When it comes to performance, NGINX can easily handle a huge amount of traffic. The other main advantage of the NGINX is that allows you to do the same thing in different ways. For me, it is a one of the best and most important service that I used in my SysAdmin career. These ...
this nonsense. gcc is just a driver program that calls other binaries to perform the actual work in a way that is defined by a set of so-called 'spec strings', which describe what commandline switches need to be passed how to which programs. This mechansim can be used to ...
Can't see dialog pics. Anonymous December 20, 2004 I love the smell of a flame war in the morning. Anonymous December 20, 2004 "Note that this is not a bad thing;"When did security by obscurity become a good thing? Someone will always find security holes and exploit them. I beleive...
Interestingly, the organizers of the research data cup identified the type of connection or attack in each data set. There are labels such as buffer_overflow, smurf or normal. This marking could serve as a target definition of a supervised learning method. However, the main focus of the ...
OpenGL allows you to draw not only to the screen, but also to a texture (through a concept called framebuffer). So we can encode particle positions as RGBA colors of an image, load it to the GPU, calculate new positions based on wind velocities in the fragment shader, encode them back...
