vkCmdPushConstants2

Alternatively, to update push constants, call:

void vkCmdPushConstants2KHR(
    VkCommandBuffer commandBuffer,
    const VkPushConstantsInfo*        pPushConstantsInfo);

commandBuffer is the command buffer in which the push constant update will be recorded.
pPushConstantsInfo is a pointer to a VkPushConstantsInfo structure.

commandBuffer must be a valid VkCommandBuffer handle

pPushConstantsInfo must be a valid pointer to a valid VkPushConstantsInfo structure

commandBuffer must be in the recording state

The VkCommandPool that commandBuffer was allocated from must support graphics, or compute operations

This command must only be called outside of a video coding scope

Host access to commandBuffer must be externally synchronized
