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.
The garbage collector works with most unmodified C programs, simply by replacing malloc() with GC_MALLOC() calls, replacing realloc() with GC_REALLOC() calls, and removing free() calls. [1] The code piece below shows how one can use Boehm instead of traditional malloc and free in C. [ 6 ]
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.
The original description of C indicated that calloc and cfree were in the standard library, but not malloc. Code for a simple model implementation of a storage manager for Unix was given with alloc and free as the user interface functions, and using the sbrk system call to request memory from the operating system. [6]
In 2000, its author Emery Berger benchmarked some famous memory allocators and stated Hoard improves the performance of multithreaded applications by providing fast, scalable memory management functions (malloc and free).
The GNU C Library, commonly known as glibc, is the GNU Project implementation of the C standard library. It provides a wrapper around the system calls of the Linux kernel and other kernels for application use. Despite its name, it now also directly supports C++ (and, indirectly, other programming languages).
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 ...
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.
