pw_malloc_freelist#

pw_malloc_freelist implements the pw_malloc facade using a freelist heap.

pw_malloc_freelist initializes a global FreeListHeapBuffer object to organize heap usage. Implementation details are in the pw_allocator module.

pw_malloc_freelist provides wrapper functions for malloc, free, realloc and calloc that uses the freelist implementation of heap in pw_allocator. In the GN build file, pw_malloc_freelist provides linker options needed in public_configs, which will be forwarded to the facade. In the case of freelist, we specify the wrapper functions malloc, free, realloc, calloc, _malloc_r, _free_r, _realloc_r, _calloc_r to replace the original libc functions at linker time.
