C Specification
Version one of the pipeline cache header is defined as:
// Provided by VK_VERSION_1_0
typedef struct VkPipelineCacheHeaderVersionOne {
uint32_t headerSize;
VkPipelineCacheHeaderVersion headerVersion;
uint32_t vendorID;
uint32_t deviceID;
uint8_t pipelineCacheUUID[VK_UUID_SIZE];
} VkPipelineCacheHeaderVersionOne;
Members
-
headerSize
is the length in bytes of the pipeline cache header. -
headerVersion
is a VkPipelineCacheHeaderVersion value specifying the version of the header. A consumer of the pipeline cache should use the cache version to interpret the remainder of the cache header. -
vendorID
is theVkPhysicalDeviceProperties
::vendorID
of the implementation. -
deviceID
is theVkPhysicalDeviceProperties
::deviceID
of the implementation. -
pipelineCacheUUID
is theVkPhysicalDeviceProperties
::pipelineCacheUUID
of the implementation.
Description
Unlike most structures declared by the Vulkan API, all fields of this structure are written with the least significant byte first, regardless of host byte-order.
The C language specification does not define the packing of structure members. This layout assumes tight structure member packing, with members laid out in the order listed in the structure, and the intended size of the structure is 32 bytes. If a compiler produces code that diverges from that pattern, applications must employ another method to set values at the correct offsets.
