  2. C dynamic memory allocation - Wikipedia

    en.wikipedia.org/wiki/C_dynamic_memory_allocation

    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.

  3. Placement syntax - Wikipedia

    en.wikipedia.org/wiki/Placement_syntax

    In the C++ programming language, placement syntax allows programmers to explicitly specify the memory management of individual objects — i.e. their "placement" in memory. Normally, when an object is created dynamically, an allocation function is invoked in such a way that it will both allocate memory for the object, and initialize the object ...

  4. Free list - Wikipedia

    en.wikipedia.org/wiki/Free_list

    This diagram represents five contiguous memory regions which each hold a pointer and a data block. The List Head points to the 2nd element, which points to the 5th, which points to the 3rd, thereby forming a linked list of available memory regions. A free list (or freelist) is a data structure used in a scheme for dynamic memory allocation.

  5. new and delete (C++) - Wikipedia

    en.wikipedia.org/wiki/New_and_delete_(C++)

    Since standard C++ subsumes the C standard library, the C dynamic memory allocation routines malloc, calloc, realloc and free are also available to C++ programmers. The use of these routines is discouraged for most uses, since they do not perform object initialization and destruction.

  6. Allocator (C++) - Wikipedia

    en.wikipedia.org/wiki/Allocator_(C++)

    [4] [15] The default allocator uses operator new to allocate memory. [16] This is often implemented as a thin layer around the C heap allocation functions, [17] which are usually optimized for infrequent allocation of large memory blocks. This approach may work well with containers that mostly allocate large chunks of memory, like vector and ...

  7. Memory pool - Wikipedia

    en.wikipedia.org/wiki/Memory_pool

    Memory pools, also called fixed-size blocks allocation, is the use of pools for memory management that allows dynamic memory allocation. Dynamic memory allocation can, and has been achieved through the use of techniques such as malloc and C++'s operator new; although established and reliable implementations, these suffer from fragmentation ...

  8. Memory management - Wikipedia

    en.wikipedia.org/wiki/Memory_management

    Memory management (also dynamic memory management, dynamic storage allocation, or dynamic memory allocation) is a form of resource management applied to computer memory.The essential requirement of memory management is to provide ways to dynamically allocate portions of memory to programs at their request, and free it for reuse when no longer needed.

  9. Region-based memory management - Wikipedia

    en.wikipedia.org/wiki/Region-based_memory_management

    In computer science, region-based memory management is a type of memory management in which each allocated object is assigned to a region. A region, also called a zone , arena , area , or memory context , is a collection of allocated objects that can be efficiently reallocated or deallocated all at once.
