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.

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.
The example C code below illustrates how structure objects are dynamically allocated and referenced. The standard C library provides the function malloc() for allocating memory blocks from the heap. It takes the size of an object to allocate as a parameter and returns a pointer to a newly allocated block of memory suitable for storing the ...
A free list (or freelist) is a data structure used in a scheme for dynamic memory allocation. It operates by connecting unallocated regions of memory together in a linked list, using the first word of each unallocated region as a pointer to the next. It is most suitable for allocating from a memory pool, where all objects have the same size.
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.
Because the data is added and removed in a last-in-first-out manner, stack-based memory allocation is very simple and typically much faster than heap-based memory allocation (also known as dynamic memory allocation) e.g. C's malloc. Another feature is that memory on the stack is automatically, and very efficiently, reclaimed when the function ...
GObject's use of GLib's g_malloc() memory allocation function will cause the program to exit unconditionally upon memory exhaustion, unlike the C library's malloc(), C++'s new, and other common memory allocators which allow a program to cope with or even fully recover from out-of-memory situations without simply crashing.
