Since FreeBSD 7.0 and NetBSD 5.0, the old malloc implementation (phkmalloc by Poul-Henning Kamp) was replaced by jemalloc, written by Jason Evans. The main reason for this was a lack of scalability of phkmalloc in terms of multithreading. In order to avoid lock contention, jemalloc uses separate "arenas" for each CPU. Experiments measuring ...
In particular, container implementations may assume that the allocator's type definitions for pointers and related integral types are equivalent to those provided by the default allocator, and that all instances of a given allocator type always compare equal, [5] [6] effectively contradicting the original design goals for allocators and ...
In computer science, manual memory management refers to the usage of manual instructions by the programmer to identify and deallocate unused objects, or garbage.Up until the mid-1990s, the majority of programming languages used in industry supported manual memory management, though garbage collection has existed since 1959, when it was introduced with Lisp.
Hosted by comedian Jeff Foxworthy, the original show asked adult contestants to answer questions typically found in elementary school quizzes with the help of actual fifth-graders as teammates ...
Many Unix-like systems as well as Microsoft Windows implement a function called alloca for dynamically allocating stack memory in a way similar to the heap-based malloc.A compiler typically translates it to inlined instructions manipulating the stack pointer, similar to how variable-length arrays are handled.

ABABABAB: Used by Microsoft's debug HeapAlloc() to mark "no man's land" guard bytes after allocated heap memory. [26] ABADBABE
