/**
 * Native bindings to the KHR_robustness extension.
 * 
 * 

Several recent trends in how OpenGL ES integrates into modern computer systems have created new requirements for robustness and security for GL * rendering contexts.

* *

Additionally GPU architectures now support hardware fault detection; for example, video memory supporting ECC (error correcting codes) and error * detection. GL contexts should be capable of recovering from hardware faults such as uncorrectable memory errors. Along with recovery from such hardware * faults, the recovery mechanism can also allow recovery from video memory access exceptions and system software failures. System software failures can * be due to device changes or driver failures.

* *

GL queries that return (write) some number of bytes to a buffer indicated by a pointer parameter introduce risk of buffer overflows that might be * exploitable by malware. To address this, queries with return value sizes that are not expressed directly by the parameters to the query itself are * given additional API functions with an additional parameter that specifies the number of bytes in the buffer and never writing bytes beyond that limit. * This is particularly useful for multi-threaded usage of GL contexts in a "share group" where one context can change objects in ways that can cause * buffer overflows for another context's GL queries.

* *

The original ARB_vertex_buffer_object extension includes an issue that explicitly states program termination is allowed when out-of-bounds vertex * buffer object fetches occur. Modern graphics hardware is capable of well-defined behavior in the case of out-of- bounds vertex buffer object fetches. * Older hardware may require extra checks to enforce well-defined (and termination free) behavior, but this expense is warranted when processing * potentially untrusted content.

* *

The intent of this extension is to address some specific robustness goals:

* *
    *
  • For all existing GL queries, provide additional "safe" APIs that limit data written to user pointers to a buffer size in bytes that is an explicit * additional parameter of the query.
  • *
  • Provide a mechanism for a GL application to learn about graphics resets that affect the context. When a graphics reset occurs, the GL context * becomes unusable and the application must create a new context to continue operation. Detecting a graphics reset happens through an inexpensive query.
  • *
  • Define behavior of OpenGL calls made after a graphics reset.
  • *
  • Provide an enable to guarantee that out-of-bounds buffer object accesses by the GPU will have deterministic behavior and preclude application * instability or termination due to an incorrect buffer access. Such accesses include vertex buffer fetches of attributes and indices, and indexed * reads of uniforms or parameters from buffers.
  • *
* *

Requires {@link GLES20 GLES 2.0}.

    *
  • {@link GLES20#GL_NO_ERROR NO_ERROR} indicates that the GL context has not been in a reset state since the last call.
  • *
  • {@link #GL_GUILTY_CONTEXT_RESET_KHR GUILTY_CONTEXT_RESET_KHR} indicates that a reset has been detected that is attributable to the current GL context.
  • *
  • {@link #GL_INNOCENT_CONTEXT_RESET_KHR INNOCENT_CONTEXT_RESET_KHR} indicates a reset has been detected that is not attributable to the current GL context.
  • *
  • {@link #GL_UNKNOWN_CONTEXT_RESET_KHR UNKNOWN_CONTEXT_RESET_KHR} indicates a detected graphics reset whose cause is unknown.
  • *
* *

If a reset status other than NO_ERROR is returned and subsequent calls return NO_ERROR, the context reset was encountered and completed. If a reset * status is repeatedly returned, the context may be in the process of resetting.

* *

Reset notification behavior is determined at context creation time, and may be queried by calling GetIntegerv with the symbolic constant * {@link #GL_RESET_NOTIFICATION_STRATEGY_KHR RESET_NOTIFICATION_STRATEGY_KHR}.

* *

If the reset notification behavior is {@link #GL_NO_RESET_NOTIFICATION_KHR NO_RESET_NOTIFICATION_KHR}, then the implementation will never deliver notification of reset events, and * GetGraphicsResetStatus will always return NO_ERROR.

* *

If the behavior is {@link #GL_LOSE_CONTEXT_ON_RESET_KHR LOSE_CONTEXT_ON_RESET_KHR}, a graphics reset will result in a lost context and require creating a new context as described * above. In this case GetGraphicsResetStatus will return an appropriate value from those described above.

* *

If a graphics reset notification occurs in a context, a notification must also occur in all other contexts which share objects with that context.

* *

After a graphics reset has occurred on a context, subsequent GL commands on that context (or any context which shares with that context) will generate a * {@link #GL_CONTEXT_LOST_KHR CONTEXT_LOST_KHR} error. Such commands will not have side effects (in particular, they will not modify memory passed by pointer for query results, * and may not block indefinitely or cause termination of the application. Exceptions to this behavior include:

* *
    *
  • {@link GLES20#glGetError GetError} and {@link #glGetGraphicsResetStatusKHR GetGraphicsResetStatusKHR} behave normally following a graphics reset, so that the application can determine a reset has * occurred, and when it is safe to destroy and recreate the context.
  • *
  • Any commands which might cause a polling application to block indefinitely will generate a {@link #GL_CONTEXT_LOST_KHR CONTEXT_LOST_KHR} error, but will also return a value * indicating completion to the application.
