```
public class VkDeviceGroupCommandBufferBeginInfo
extends org.lwjgl.system.Struct
implements org.lwjgl.system.NativeResource
```
Set the initial device mask for a command buffer.
Description

The initial device mask also acts as an upper bound on the set of devices that can ever be in the device mask in the command buffer.

If this structure is not present, the initial value of a command buffer’s device mask is set to include all physical devices in the logical device when the command buffer begins recording.

Valid Usage
- deviceMask must be a valid device mask value
- deviceMask must not be zero
Valid Usage (Implicit)
- sType must be STRUCTURE_TYPE_DEVICE_GROUP_COMMAND_BUFFER_BEGIN_INFO
Layout
```
 struct VkDeviceGroupCommandBufferBeginInfo {
     VkStructureType sType();
     void const * pNext();
     uint32_t deviceMask();
 }
```
