C Specification
VkShaderModuleCreateInfo structures have unique identifiers associated with them. To query an implementation provided identifier, call:
// Provided by VK_EXT_shader_module_identifier
void vkGetShaderModuleCreateInfoIdentifierEXT(
VkDevice device,
const VkShaderModuleCreateInfo* pCreateInfo,
VkShaderModuleIdentifierEXT* pIdentifier);
Parameters
-
device
is the logical device that can create a VkShaderModule frompCreateInfo
. -
pCreateInfo
is a pointer to a VkShaderModuleCreateInfo structure. -
pIdentifier
is a pointer to the returned VkShaderModuleIdentifierEXT.
Description
The identifier returned by implementation must only depend on
shaderIdentifierAlgorithmUUID
and information provided in the
VkShaderModuleCreateInfo.
The implementation may return equal identifiers for two different
VkShaderModuleCreateInfo structures if the difference does not affect
pipeline compilation.
Identifiers are only meaningful on different VkDevice objects if the
device the identifier was queried from had the same
shaderModuleIdentifierAlgorithmUUID
as the device consuming the
identifier.
The identifier returned by the implementation in
vkGetShaderModuleCreateInfoIdentifierEXT must be equal to the
identifier returned by vkGetShaderModuleIdentifierEXT given equivalent
definitions of VkShaderModuleCreateInfo and any chained pNext
structures.
