   <div id="projectbrief">This is a minimal-state, immediate-mode graphical user interface toolkit written in ANSI C and licensed under public domain. It was designed as a simple embeddable user interface for application and does not have any dependencies, a default render backend or OS window/input handling but instead provides a highly modular, library-based approach, with simple input state for input and draw commands describing primitive shapes as output. So instead of providing a layered library that tries to abstract over a number of platform and render backends, it focuses only on the actual UI.</div>

<pre class="fragment">                    MEMORY BUFFER
</pre><p> ===============================================================</p>
<p>A basic (double)-buffer with linear allocation and resetting as only freeing policy. The buffer's main purpose is to control all memory management inside the GUI toolkit and still leave memory control as much as possible in the hand of the user while also making sure the library is easy to use if not as much control is needed. In general all memory inside this library can be provided from the user in three different ways.</p>
<p>The first way and the one providing most control is by just passing a fixed size memory block. In this case all control lies in the hand of the user since he can exactly control where the memory comes from and how much memory the library should consume. Of course using the fixed size API removes the ability to automatically resize a buffer if not enough memory is provided so you have to take over the resizing. While being a fixed sized buffer sounds quite limiting, it is very effective in this library since the actual memory consumption is quite stable and has a fixed upper bound for a lot of cases.</p>
<p>If you don't want to think about how much memory the library should allocate at all time or have a very dynamic UI with unpredictable memory consumption habits but still want control over memory allocation you can use the dynamic allocator based API. The allocator consists of two callbacks for allocating and freeing memory and optional userdata so you can plugin your own allocator.</p>
<p>The final and easiest way can be used by defining NK_INCLUDE_DEFAULT_ALLOCATOR which uses the standard library memory allocation functions malloc and free and takes over complete control over memory in this library. </p>
