The C programming language manages memory statically, automatically, or dynamically.Static-duration variables are allocated in main memory, usually along with the executable code of the program, and persist for the lifetime of the program; automatic-duration variables are allocated on the stack and come and go as functions are called and return.
The Hoard memory allocator, or Hoard, is a memory allocator for Linux, OS X, and Microsoft Windows. Hoard is designed to be efficient when used by multithreaded applications on multiprocessor computers. Hoard is distributed under the Apache License, version 2.0.
Address space layout randomization (ASLR) is a computer security technique involved in preventing exploitation of memory corruption vulnerabilities. [1] In order to prevent an attacker from reliably redirecting code execution to, for example, a particular exploited function in memory, ASLR randomly arranges the address space positions of key data areas of a process, including the base of the ...
mimalloc (pronounced "me-malloc") is a free and open-source compact general-purpose memory allocator developed by Microsoft [2] with focus on performance characteristics. The library is about 11000 lines of code and works as a drop-in replacement for malloc of the C standard library [3] and requires no additional code changes.
musl is a C standard library intended for operating systems based on the Linux kernel, released under the MIT License. [3] It was developed by Rich Felker to write a clean, efficient, and standards-conformant libc implementation.
Most Linux machines come with a console command called mtrace, that converts the computer readable format into human-readable text as shown below. If you do not have access to this console command, there is a Perl script, of the same name, that can be downloaded to accomplish the same task.
These functions are typically called from a higher-level memory management library function such as malloc. In the original Unix system, brk and sbrk were the only ways in which applications could acquire additional heap space; later versions allowed this to also be done using the mmap call.
The Linux kernel also uses the buddy system, with further modifications to minimise external fragmentation, along with various other allocators to manage the memory within blocks. [ 3 ] jemalloc [ 4 ] is a modern memory allocator that employs, among others, the buddy technique.
