    Buddy allocator backed by a Buffer.

    This is likely less efficient than allocating new Buffers and letting them be garbage-collected. You should probably never use this for anything serious, unless you are confident that this will solve your very particular problem, or you simply miss the good ol' days of manual memory management.

    Install

    npm install alloc
    

    Use

    Configure a new buddy allocator. Optional minSize can be used to limit the smallest block that the allocator will allocate (defaults to 1); any requests for fewer than minSize bytes will still use up a minSize block.

    var BuddyAllocator = require('alloc').BuddyAllocator;
    var buddy = new BuddyAllocator(16384, {minSize: 16});

    Allocate some blocks, and remember to free them later.

    var block = buddy.alloc(960);
    buddy.free(block);

    Keep an eye on internal fragmentation with powerful analytics tools!

    var frag = buddy.bytesWasted / buddy.bytesAllocated;
    console.log('Internal fragmentation: %d%%', frag * 100);
