VkWin32KeyedMutexAcquireReleaseInfoKHR - Use the Windows keyed mutex mechanism to synchronize work

Valid Usage

• Each member of pAcquireSyncs and pReleaseSyncs must be a device memory object imported by setting ImportMemoryWin32HandleInfoKHR::handleType to EXTERNAL_MEMORY_HANDLE_TYPE_D3D11_TEXTURE_BIT or EXTERNAL_MEMORY_HANDLE_TYPE_D3D11_TEXTURE_KMT_BIT.

Valid Usage (Implicit)

• sType must be STRUCTURE_TYPE_WIN32_KEYED_MUTEX_ACQUIRE_RELEASE_INFO_KHR

• If acquireCount is not 0, pAcquireSyncs must be a valid pointer to an array of acquireCount valid DeviceMemory handles
• If acquireCount is not 0, pAcquireKeys must be a valid pointer to an array of acquireCount uint64_t values
• If acquireCount is not 0, pAcquireTimeouts must be a valid pointer to an array of acquireCount uint32_t values
• If releaseCount is not 0, pReleaseSyncs must be a valid pointer to an array of releaseCount valid DeviceMemory handles
• If releaseCount is not 0, pReleaseKeys must be a valid pointer to an array of releaseCount uint64_t values
• Both of the elements of pAcquireSyncs, and the elements of pReleaseSyncs that are valid handles of non-ignored parameters must have been created, allocated, or retrieved from the same Device
