C Specification

To create a semaphore whose payload can be exported to external handles, add a VkExportSemaphoreCreateInfo structure to the pNext chain of the VkSemaphoreCreateInfo structure. The VkExportSemaphoreCreateInfo structure is defined as:

// Provided by VK_VERSION_1_1
typedef struct VkExportSemaphoreCreateInfo {
    VkStructureType                       sType;
    const void*                           pNext;
    VkExternalSemaphoreHandleTypeFlags    handleTypes;
} VkExportSemaphoreCreateInfo;

or the equivalent

// Provided by VK_KHR_external_semaphore
typedef VkExportSemaphoreCreateInfo VkExportSemaphoreCreateInfoKHR;


  • sType is a VkStructureType value identifying this structure.

  • pNext is NULL or a pointer to a structure extending this structure.

  • handleTypes is a bitmask of VkExternalSemaphoreHandleTypeFlagBits specifying one or more semaphore handle types the application can export from the resulting semaphore. The application can request multiple handle types for the same semaphore.


Valid Usage
  • VUID-VkExportSemaphoreCreateInfo-handleTypes-01124
    The bits in handleTypes must be supported and compatible, as reported by VkExternalSemaphoreProperties

Valid Usage (Implicit)
  • VUID-VkExportSemaphoreCreateInfo-sType-sType

  • VUID-VkExportSemaphoreCreateInfo-handleTypes-parameter
    handleTypes must be a valid combination of VkExternalSemaphoreHandleTypeFlagBits values
