In C and C++, it can be very convenient to allocate and de-allocate blocks of memory as and when needed. This is certainly standard practice in both languages and almost unavoidable in C++. However, ...
A topic that I find particularly interesting, which is raised by many embedded software developers whom I meet, is dynamic memory allocation – grabbing chunks of memory as and when you need them. This ...
“Fragmented memory” describes all of a system’s unusable free memory. These resources remain unused because the memory allocator responsible for allocating them cannot make the memory available. This ...
I recently presented arguments for and against using dynamic memory allocation in C and C++ programs. 1 I do agree that truly safety-critical systems should avoid using dynamic allocation because the ...
Memory management is a critical aspect of modern operating systems, ensuring efficient allocation and deallocation of system memory. Linux, as a robust and widely used operating system, employs ...
Unfortunately for kernel developers, allocating memory in the kernel is not as simple as allocating memory in user space. A number of factors contribute to the complication, among them: The kernel is ...
If your production Linux system is logging memory allocation failures, it might still be able to keep running. But developers want to keep an eye on which code can survive a shortage of memory. In ...
