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.
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.
This is a list of commands from the GNU Core Utilities for Unix environments. These commands can be found on Unix operating systems and most Unix-like operating systems. GNU Core Utilities include basic file, shell and text manipulation utilities. Coreutils includes all of the basic command-line tools that are expected in a POSIX system.
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.
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 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.
Memory pools allow memory allocation with constant execution time. The memory release for thousands of objects in a pool is just one operation, not one by one if malloc is used to allocate memory for each object. Memory pools can be grouped in hierarchical tree structures, which is suitable for special programming structures like loops and ...
The free list may be a separate data structure, such as an array of indices indicating which entries of the slab are free, or it may be embedded within the slab. The Linux SLUB allocator keeps the free list as a linked list of pointers, each of which is stored directly in the free memory area of the slab they represent. [6]
