# VkPhysicalDeviceExternalSemaphoreInfo(3) Manual Page

## Name

VkPhysicalDeviceExternalSemaphoreInfo - Structure specifying semaphore creation parameters.

## C Specification

The `VkPhysicalDeviceExternalSemaphoreInfo` structure is defined as:

    typedef struct VkPhysicalDeviceExternalSemaphoreInfo {
        VkStructureType                          sType;
        const void*                              pNext;
        VkExternalSemaphoreHandleTypeFlagBits    handleType;
    } VkPhysicalDeviceExternalSemaphoreInfo;

or the equivalent

    typedef VkPhysicalDeviceExternalSemaphoreInfo VkPhysicalDeviceExternalSemaphoreInfoKHR;

## Members

- `sType` is the type of this structure

- `pNext` is NULL or a pointer to an extension-specific structure.

- `handleType` is a VkExternalSemaphoreHandleTypeFlagBits value specifying the external semaphore handle type for which capabilities will be returned.

## Description

Valid Usage (Implicit)

- `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_EXTERNAL_SEMAPHORE_INFO`

- `pNext` must be `NULL` or a pointer to a valid instance of VkSemaphoreTypeCreateInfo

- The `sType` value of each struct in the `pNext` chain must be unique

- `handleType` must be a valid VkExternalSemaphoreHandleTypeFlagBits value
