Description

The handle types supported by handleType are:

Handle Types Supported by VkImportFenceFdInfoKHR

Handle Type Transference Permanence Supported

EXTERNAL_FENCE_HANDLE_TYPE_OPAQUE_FD_BIT Reference Temporary,Permanent

EXTERNAL_FENCE_HANDLE_TYPE_SYNC_FD_BIT Copy Temporary

Valid Usage
- handleType must be a value included in the Handle Types Supported by VkImportFenceFdInfoKHR table.
- fd must obey any requirements listed for handleType in external fence handle types compatibility.
If handleType is EXTERNAL_FENCE_HANDLE_TYPE_SYNC_FD_BIT, the special value -1 for fd is treated like a valid sync file descriptor referring to an object that has already signaled. The import operation will succeed and the VkFence will have a temporarily imported payload as if a valid file descriptor had been provided.

Note

This special behavior for importing an invalid sync file descriptor allows easier interoperability with other system APIs which use the convention that an invalid sync file descriptor represents work that has already completed and does not need to be waited for. It is consistent with the option for implementations to return a -1 file descriptor when exporting a EXTERNAL_FENCE_HANDLE_TYPE_SYNC_FD_BIT from a VkFence which is signaled.

Valid Usage (Implicit)
- sType must be STRUCTURE_TYPE_IMPORT_FENCE_FD_INFO_KHR
- pNext must be NULL
- fence must be a valid VkFence handle
- flags must be a valid combination of VkFenceImportFlagBits values
- handleType must be a valid VkExternalFenceHandleTypeFlagBits value
Host Synchronization
- Host access to fence must be externally synchronized

Member documentation
- sType – the type of this structure.
- pNext – NULL or a pointer to an extension-specific structure.
- fence – the fence into which the payload will be imported.
- flags – a bitmask of VkFenceImportFlagBits specifying additional parameters for the fence payload import operation.
- handleType – specifies the type of fd.
- fd – the external handle to import.
