Function Prototype
vkDestroySemaphore
Destroy a semaphore object
To destroy a semaphore, call:
void vkDestroySemaphore(
VkDevice device,
VkSemaphore semaphore,
const VkAllocationCallbacks* pAllocator);
device
is the logical device that destroys the semaphore.semaphore
is the handle of the semaphore to destroy.pAllocator
controls host memory allocation as described in the Memory Allocation chapter.
Valid Usage
VUID-vkDestroySemaphore-semaphore-05149
All
submitted batches that refer to semaphore
must have completed
execution
VUID-vkDestroySemaphore-semaphore-01138
If VkAllocationCallbacks
were provided when semaphore
was
created, a compatible set of callbacks must be provided here
VUID-vkDestroySemaphore-semaphore-01139
If no VkAllocationCallbacks
were provided when semaphore
was
created, pAllocator
must be NULL
Valid Usage (Implicit)
VUID-vkDestroySemaphore-device-parameter
device
must be a valid VkDevice handle
VUID-vkDestroySemaphore-semaphore-parameter
If semaphore
is not VK_NULL_HANDLE, semaphore
must be a valid VkSemaphore handle
VUID-vkDestroySemaphore-pAllocator-parameter
If pAllocator
is not NULL
, pAllocator
must be a valid pointer to a valid VkAllocationCallbacks structure
VUID-vkDestroySemaphore-semaphore-parent
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 ::
