Memory Allocation

[RobLoach]

Use Nuklear's memory allocator. For example.....

NK_LIB struct nk_page_element*
nk_create_page_element(struct nk_context *ctx)
{
    struct nk_page_element *elem;
    if (ctx->freelist) {
        /* unlink page element from free list */
        elem = ctx->freelist;
        ctx->freelist = elem->next;
    } else if (ctx->use_pool) {
        /* allocate page element from memory pool */
        elem = nk_pool_alloc(&ctx->pool);
        NK_ASSERT(elem);
        if (!elem) return 0;
    } else {
        /* allocate new page element from back of fixed size memory buffer */
        NK_STORAGE const nk_size size = sizeof(struct nk_page_element);
        NK_STORAGE const nk_size align = NK_ALIGNOF(struct nk_page_element);
        elem = (struct nk_page_element*)nk_buffer_alloc(&ctx->memory, NK_BUFFER_BACK, size, align);
        NK_ASSERT(elem);
        if (!elem) return 0;
    }
    nk_zero_struct(*elem);
    elem->next = 0;
    elem->prev = 0;
    return elem;
}
