Detailed Description

Memory block management with Red-Black tree based allocator.

This file implements a memory block that uses a Red-Black tree to track free memory regions and provides efficient allocation/deallocation.

Macro Definition Documentation

#define MEMORY_NODE_SIZE sizeof(MemoryNode)

Size of the MemoryNode metadata structure.

#define RELEASE_MEMORY_VIA_MUNMAP	(	ptr,
		size
	)	munmap(ptr, size)

Releases memory back to the operating system using munmap.

Parameters

ptr	Pointer to memory to release
size	Size in bytes to release

#define REQUEST_MEMORY_VIA_MMAP ( size ) mmap(nullptr, size, PROT_READ | PROT_WRITE, MAP_PRIVATE | MAP_ANONYMOUS, -1, 0)

Allocates memory from the operating system using mmap.

Parameters

size	Size in bytes to allocate
