public class VkSemaphoreGetFdInfoKHR
extends org.lwjgl.system.Struct
implements org.lwjgl.system.NativeResource
```
Structure describing a POSIX FD semaphore export operation.
Description

The properties of the file descriptor returned depend on the value of handleType. See VkExternalSemaphoreHandleTypeFlagBits for a description of the properties of the defined external semaphore handle types.

Valid Usage
- handleType must have been included in VkExportSemaphoreCreateInfo::handleTypes when semaphore’s current payload was created.
- semaphore must not currently have its payload replaced by an imported payload as described below in Importing Semaphore Payloads unless that imported payload’s handle type was included in VkExternalSemaphoreProperties::exportFromImportedHandleTypes for handleType.
- If handleType refers to a handle type with copy payload transference semantics, as defined below in Importing Semaphore Payloads, there must be no queue waiting on semaphore.
- If handleType refers to a handle type with copy payload transference semantics, semaphore must be signaled, or have an associated semaphore signal operation pending execution.
- handleType must be defined as a POSIX file descriptor handle.
Valid Usage (Implicit)
- sType must be STRUCTURE_TYPE_SEMAPHORE_GET_FD_INFO_KHR
- pNext must be NULL
- semaphore must be a valid VkSemaphore handle
- handleType must be a valid VkExternalSemaphoreHandleTypeFlagBits value

Member documentation
- sType – the type of this structure.
- pNext – NULL or a pointer to an extension-specific structure.
- semaphore – the semaphore from which state will be exported.
- handleType – the type of handle requested.
