VkFenceGetFdInfoKHR(3)

Name

VkFenceGetFdInfoKHR - Structure describing a POSIX FD fence export operation

C Specification

TheVkFenceGetFdInfoKHR structure is defined as:

// Provided by VK_KHR_external_fence_fdtypedef struct VkFenceGetFdInfoKHR {    VkStructureType                      sType;    const void*                          pNext;    VkFence                              fence;    VkExternalFenceHandleTypeFlagBits    handleType;} VkFenceGetFdInfoKHR;

Members

sType is aVkStructureType value identifying this structure.
pNext isNULL or a pointer to a structure extending thisstructure.
fence is the fence from which state will be exported.
handleType is aVkExternalFenceHandleTypeFlagBits valuespecifying the type of handle requested.

Description

The properties of the file descriptor returned depend on the value ofhandleType.SeeVkExternalFenceHandleTypeFlagBits for a description of theproperties of the defined external fence handle types.

Valid Usage

VUID-VkFenceGetFdInfoKHR-handleType-01453
handleTypemust have been included inVkExportFenceCreateInfo::handleTypes whenfence’scurrent payload was created
VUID-VkFenceGetFdInfoKHR-handleType-01454
IfhandleType refers to a handle type with copy payloadtransference semantics,fencemust be signaled, or have anassociatedfence signal operationpending execution
VUID-VkFenceGetFdInfoKHR-fence-01455
fencemust not currently have its payload replaced by an importedpayload as described below inImporting Fence Payloads unlessthat imported payload’s handle type was included inVkExternalFenceProperties::exportFromImportedHandleTypes forhandleType
VUID-VkFenceGetFdInfoKHR-handleType-01456
handleTypemust be defined as a POSIX file descriptor handle

Valid Usage (Implicit)

VUID-VkFenceGetFdInfoKHR-sType-sType
sTypemust beVK_STRUCTURE_TYPE_FENCE_GET_FD_INFO_KHR
VUID-VkFenceGetFdInfoKHR-pNext-pNext
pNextmust beNULL
VUID-VkFenceGetFdInfoKHR-fence-parameter
fencemust be a validVkFence handle
VUID-VkFenceGetFdInfoKHR-handleType-parameter
handleTypemust be a validVkExternalFenceHandleTypeFlagBits value
