WGLARBPbuffer (LWJGL 3.2.4 SNAPSHOT

java.lang.Object
- org.lwjgl.opengl.WGLARBPbuffer

```
public class WGLARBPbuffer
extends java.lang.Object
```
Native bindings to the WGL_ARB_pbuffer extension.
This extension defines pixel buffers (pbuffer for short). Pbuffers are additional non-visible rendering buffers for an OpenGL renderer. Pbuffers are equivalent to a window that has the same pixel format descriptor with the following exceptions:
1. There is no rendering to a pbuffer by GDI.
2. The pixel format descriptors used for a pbuffer can only be those that are supported by the ICD. Generic formats are not valid.
3. The allocation of a pbuffer can fail if there are insufficient resources (i.e., all the pbuffer memory has been allocated).
4. The pixel buffer might be lost if a display mode change occurs. A query is provided that can be called after a display mode change to determine the state of the pixel buffer.
The intent of the pbuffer semantics is to enable implementations to allocate pbuffers in non-visible frame buffer memory. These pbuffers are intended to be "static" resources in that a program will typically allocate them only once rather than as a part of its rendering loop. (Pbuffers should be deallocated when the program is no longer using them -- for example, if the program is iconified.)

The frame buffer resources that are associated with a pbuffer are also static and are deallocated when the pbuffer is destroyed or possibly when a display mode change occurs.

Requires WGL_ARB_extensions_string and WGL_ARB_pixel_format.

                                       int width,

```
    Creates a pixel buffer (pbuffer) and returns a handle to it.
    Support for pbuffers may be restricted to specific pixel formats. Use GetPixelFormatAttribivARB to query the DRAW_TO_PBUFFER_ARB attribute to determine which pixel formats support the creation of pbuffers.
    
    Parameters:
    
    hdc - a device context for the device on which the pbuffer is created
    
    pixelFormat - a non-generic pixel format descriptor index
    
    width - the pixel width of the rectangular pbuffer
    
    height - the pixel height of the rectangular pbuffer
    
    attribList - a 0-terminated list of attributes {type, value} pairs containing integer attribute values
  - wglGetPbufferDCARB
```
public static long wglGetPbufferDCARB(long pbuffer)
```
    Creates a device context for the pbuffer.
    
    Parameters:
    
    pbuffer - a pbuffer handle returned from a previous call to CreatePbufferARB
  - wglReleasePbufferDCARB
```
public static int wglReleasePbufferDCARB(long pbuffer,
                                         long hdc)
```
    Releases a device context obtained from a previous call to GetPbufferDCARB.
    
    Parameters:
    
    pbuffer - a pbuffer handle
    
    hdc - a device context handle
  - wglDestroyPbufferARB
```
public static boolean wglDestroyPbufferARB(long pbuffer)
```
    Destroys a pbuffer.
    The pbuffer is destroyed once it is no longer current to any rendering context. When a pbuffer is destroyed, any memory resources that are attached to it are freed and its handle is no longer valid.
    
    Parameters:
    
    pbuffer - a pbuffer handle
  - nwglQueryPbufferARB
```
public static int nwglQueryPbufferARB(long pbuffer,
                                      int attribute,
                                      long value)
```
    Unsafe version of: QueryPbufferARB
  - wglQueryPbufferARB
```
public static boolean wglQueryPbufferARB(long pbuffer,
                                         int attribute,
                                         java.nio.IntBuffer value)
```
    Queries an attribute associated with a specific pbuffer.
    
    Parameters:
    
    pbuffer - a pbuffer handle
    
    attribute - the attribute to query. One of:
    PBUFFER_WIDTH_ARB PBUFFER_HEIGHT_ARB PBUFFER_LOST_ARB
    
    value - the attribute value
