Create a new sync file descriptor for the underlying fence. The fence must already be signaled or have a signal operation pending in a queue. There are no checks for this in the implementation and only Vulkan validation will catch such a misuse and undefined behavior. More... | |

fml::UniqueFD impeller::ExternalFenceVK::CreateFD | ( | ) | const |
Create a new sync file descriptor for the underlying fence. The fence must already be signaled or have a signal operation pending in a queue. There are no checks for this in the implementation and only Vulkan validation will catch such a misuse and undefined behavior.
Since this call can return an invalid FD even in case of success, make sure to make the IsValid
check before attempting to export a FD.
