createSemaphore

Arguments

:: forall a io. (Extendss SemaphoreCreateInfo a, PokeChain a, MonadIO io)

=> Device

device is the logical device that creates the semaphore.

-> SemaphoreCreateInfo a

pCreateInfo is a pointer to a SemaphoreCreateInfo structure containing information about how the semaphore is to be created.

-> ("allocator" ::: Maybe AllocationCallbacks)

pAllocator controls host memory allocation as described in the Memory Allocation chapter.

-> io Semaphore

vkCreateSemaphore - Create a new queue semaphore object

Valid Usage (Implicit)

• device must be a valid Device handle

• pCreateInfo must be a valid pointer to a valid SemaphoreCreateInfo structure
• If pAllocator is not NULL, pAllocator must be a valid pointer to a valid AllocationCallbacks structure
• pSemaphore must be a valid pointer to a Semaphore handle

Return Codes

Success

• SUCCESS

Failure

• ERROR_OUT_OF_HOST_MEMORY
• ERROR_OUT_OF_DEVICE_MEMORY

withSemaphore :: forall a io r. (Extendss SemaphoreCreateInfo a, PokeChain a, MonadIO io) => Device -> SemaphoreCreateInfo a -> Maybe AllocationCallbacks -> (io Semaphore -> (Semaphore -> io ()) -> r) -> r

A convenience wrapper to make a compatible pair of calls to createSemaphore and destroySemaphore

To ensure that destroySemaphore is always called: pass bracket (or the allocate function from your favourite resource management library) as the last argument. To just extract the pair pass (,) as the last argument.

destroySemaphore

Arguments

:: forall io. MonadIO io

=> Device

device is the logical device that destroys the semaphore.

-> Semaphore

semaphore is the handle of the semaphore to destroy.

-> ("allocator" ::: Maybe AllocationCallbacks)

pAllocator controls host memory allocation as described in the Memory Allocation chapter.

-> io ()

vkDestroySemaphore - Destroy a semaphore object

Valid Usage

• All submitted batches that refer to semaphore must have completed execution

• If AllocationCallbacks were provided when semaphore was created, a compatible set of callbacks must be provided here
• If no AllocationCallbacks were provided when semaphore was created, pAllocator must be NULL

Valid Usage (Implicit)

• device must be a valid Device handle

• If semaphore is not NULL_HANDLE, semaphore must be a valid Semaphore handle
• If pAllocator is not NULL, pAllocator must be a valid pointer to a valid AllocationCallbacks structure
• If semaphore is a valid handle, it must have been created, allocated, or retrieved from device

Host Synchronization

• Host access to semaphore must be externally synchronized

data SemaphoreCreateInfo (es :: [Type])

VkSemaphoreCreateInfo - Structure specifying parameters of a newly created semaphore

Valid Usage (Implicit)

• sType must be STRUCTURE_TYPE_SEMAPHORE_CREATE_INFO

• Each pNext member of any structure (including this one) in the pNext chain must be either NULL or a pointer to a valid instance of ExportSemaphoreCreateInfo, ExportSemaphoreWin32HandleInfoKHR, or SemaphoreTypeCreateInfo
• The sType value of each struct in the pNext chain must be unique
• flags must be 0

Fields

• next :: Chain es

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

• flags :: SemaphoreCreateFlags
