Name

vkCmdDecompressMemoryEXT - Decompress data between memory regions

C Specification

To decompress memory containing compressed data, call:

// Provided by VK_EXT_memory_decompression
void vkCmdDecompressMemoryEXT(
    VkCommandBuffer                             commandBuffer,
    const VkDecompressMemoryInfoEXT*            pDecompressMemoryInfoEXT);

Parameters

commandBuffer is the command buffer into which the command will be recorded.
pDecompressMemoryInfoEXT is a pointer to a VkDecompressMemoryInfoEXT structure describing the decompression parameters.
