## C Specification

The VkValidationCacheCreateInfoEXT structure is defined as:

typedef struct VkValidationCacheCreateInfoEXT {
VkStructureType                    sType;
const void*                        pNext;
VkValidationCacheCreateFlagsEXT    flags;
size_t                             initialDataSize;
const void*                        pInitialData;
} VkValidationCacheCreateInfoEXT;

## Members

• sType is the type of this structure.

• pNext is NULL or a pointer to an extension-specific structure.

• flags is reserved for future use.

• initialDataSize is the number of bytes in pInitialData. If initialDataSize is zero, the validation cache will initially be empty.

• pInitialData is a pointer to previously retrieved validation cache data. If the validation cache data is incompatible (as defined below) with the device, the validation cache will be initially empty. If initialDataSize is zero, pInitialData is ignored.

## Description

Valid Usage
• If initialDataSize is not 0, it must be equal to the size of pInitialData, as returned by vkGetValidationCacheDataEXT when pInitialData was originally retrieved

• If initialDataSize is not 0, pInitialData must have been retrieved from a previous call to vkGetValidationCacheDataEXT

Valid Usage (Implicit)
• sType must be VK_STRUCTURE_TYPE_VALIDATION_CACHE_CREATE_INFO_EXT

• pNext must be NULL

• flags must be 0

• If initialDataSize is not 0, pInitialData must be a valid pointer to an array of initialDataSize bytes
