All Implemented Interfaces:

```
public class VkConditionalRenderingBeginInfoEXT
extends Struct
implements NativeResource
```
Structure specifying conditional rendering begin info.
Description

If the 32-bit value at offset in buffer memory is zero, then the rendering commands are discarded, otherwise they are executed as normal. If the value of the predicate in buffer memory changes while conditional rendering is active, the rendering commands may be discarded in an implementation-dependent way. Some implementations may latch the value of the predicate upon beginning conditional rendering while others may read it before every rendering command.

Valid Usage
- If buffer is non-sparse then it must be bound completely and contiguously to a single VkDeviceMemory object
- buffer must have been created with the BUFFER_USAGE_CONDITIONAL_RENDERING_BIT_EXT bit set
- offset must be less than the size of buffer by at least 32 bits.
- offset must be a multiple of 4
Valid Usage (Implicit)
- sType must be STRUCTURE_TYPE_CONDITIONAL_RENDERING_BEGIN_INFO_EXT
- pNext must be NULL
- buffer must be a valid VkBuffer handle
- flags must be a valid combination of VkConditionalRenderingFlagBitsEXT values
