public final class KHRVariablePointers extends Object
The VK_KHR_variable_pointers extension allows implementations to indicate their level of support for the SPV_KHR_variable_pointers SPIR-V extension. The SPIR-V extension allows shader modules to use invocation-private pointers into uniform and/or storage buffers, where the pointer values can be dynamic and non-uniform.

The SPV_KHR_variable_pointers extension introduces two capabilities. The first, VariablePointersStorageBuffer, must be supported by all implementations of this extension. The second, VariablePointers, is optional.

Promotion to Vulkan 1.1

All functionality in this extension is included in core Vulkan 1.1, with the KHR suffix omitted, however support for the variablePointersStorageBuffer feature is made optional. The original type, enum and command names are still available as aliases of the core functionality.
