## C Specification

The `VkDispatchIndirectCommand` structure is defined as:

    // Provided by VK_VERSION_1_0
    typedef struct VkDispatchIndirectCommand {
        uint32_t    x;
        uint32_t    y;
        uint32_t    z;
    } VkDispatchIndirectCommand;

## Members

- `x` is the number of local workgroups to dispatch in the X dimension.

- `y` is the number of local workgroups to dispatch in the Y dimension.

- `z` is the number of local workgroups to dispatch in the Z dimension.

## Description

The members of `VkDispatchIndirectCommand` have the same meaning as the corresponding parameters of vkCmdDispatch.

Valid Usage

  `x` must be less than or equal to `VkPhysicalDeviceLimits`::`maxComputeWorkGroupCount`[0]

- VUID-VkDispatchIndirectCommand-y-00418
  `y` must be less than or equal to `VkPhysicalDeviceLimits`::`maxComputeWorkGroupCount`[1]

- VUID-VkDispatchIndirectCommand-z-00419
