C Specification
To export a NvSciSyncFence
handle representing the payload of a fence,
call:
// Provided by VK_NV_external_sci_sync, VK_NV_external_sci_sync2
VkResult vkGetFenceSciSyncFenceNV(
VkDevice device,
const VkFenceGetSciSyncInfoNV* pGetSciSyncHandleInfo,
void* pHandle);
Parameters
-
device
is the logical device that created the fence being exported. -
pGetSciSyncHandleInfo
is a pointer to a VkFenceGetSciSyncInfoNV structure containing parameters of the export operation. -
pHandle
is a pointer to aNvSciSyncFence
which will contain the fence payload on return.
Description
Each call to vkGetFenceSciSyncFenceNV
will duplicate the underlying
NvSciSyncFence
handle and transfer the ownership of the
NvSciSyncFence
handle to the application.
To avoid leaking resources, the application must release of the ownership
of the NvSciSyncFence
handle when it is no longer needed.
