vkCreateValidationCacheEXT

To create validation cache objects, call:

VkResult vkCreateValidationCacheEXT(
    VkDevice device,
    const VkValidationCacheCreateInfoEXT* pCreateInfo,
    const VkAllocationCallbacks* pAllocator,
    VkValidationCacheEXT* pValidationCache);

• device is the logical device that creates the validation cache object.
• pCreateInfo is a pointer to a VkValidationCacheCreateInfoEXT structure containing the initial parameters for the validation cache object.
• pAllocator controls host memory allocation as described in the Memory Allocation chapter.
• pValidationCache is a pointer to a VkValidationCacheEXT handle in which the resulting validation cache object is returned.

Once created, a validation cache can be passed to the vkCreateShaderModule command by adding this object to the VkShaderModuleCreateInfo structure’s pNext chain. If a VkShaderModuleValidationCacheCreateInfoEXT object is included in the VkShaderModuleCreateInfo::pNext chain, and its validationCache field is not VK_NULL_HANDLE, the implementation will query it for possible reuse opportunities and update it with new content. The use of the validation cache object in these commands is internally synchronized, and the same validation cache object can be used in multiple threads simultaneously.
