VkFenceGetFdInfoKHR
The VkFenceGetFdInfoKHR
structure is defined as:
typedef struct VkFenceGetFdInfoKHR {
VkStructureType sType;
const void* pNext;
VkFence fence;
VkExternalFenceHandleTypeFlagBits handleType;
} VkFenceGetFdInfoKHR;
sType
is a VkStructureType value identifying this structure.pNext
isNULL
or a pointer to a structure extending this structure.fence
is the fence from which state will be exported.handleType
is a VkExternalFenceHandleTypeFlagBits value specifying the type of handle requested.
The properties of the file descriptor returned depend on the value of
handleType
.
See VkExternalFenceHandleTypeFlagBits for a description of the
properties of the defined external fence handle types.
Valid Usage
VUID-VkFenceGetFdInfoKHR-handleType-01453
handleType
must have been included in
VkExportFenceCreateInfo::handleTypes
when fence
’s
current payload was created
VUID-VkFenceGetFdInfoKHR-handleType-01454
If handleType
refers to a handle type with copy payload
transference semantics, fence
must be signaled, or have an
associated fence signal operation
pending execution
VUID-VkFenceGetFdInfoKHR-fence-01455
fence
must not currently have its payload replaced by an imported
payload as described below in
Importing Fence Payloads unless
that imported payload’s handle type was included in
VkExternalFenceProperties::exportFromImportedHandleTypes
for
handleType
VUID-VkFenceGetFdInfoKHR-handleType-01456
handleType
must be defined as a POSIX file descriptor handle
Valid Usage (Implicit)
VUID-VkFenceGetFdInfoKHR-sType-sType
sType
must be VK_STRUCTURE_TYPE_FENCE_GET_FD_INFO_KHR
VUID-VkFenceGetFdInfoKHR-pNext-pNext
pNext
must be NULL
VUID-VkFenceGetFdInfoKHR-fence-parameter
fence
must be a valid VkFence handle
VUID-VkFenceGetFdInfoKHR-handleType-parameter
handleType
must be a valid VkExternalFenceHandleTypeFlagBits value
