vkDestroySampler

To destroy a sampler, call:

void vkDestroySampler(
    VkDevice device,
    VkSampler sampler,
    const VkAllocationCallbacks* pAllocator);

device is the logical device that destroys the sampler.
sampler is the sampler to destroy.
pAllocator controls host memory allocation as described in the Memory Allocation chapter.

All submitted commands that refer to sampler must have completed execution

If VkAllocationCallbacks were provided when sampler was created, a compatible set of callbacks must be provided here

If no VkAllocationCallbacks were provided when sampler was created, pAllocator must be NULL

device must be a valid VkDevice handle

If sampler is not VK_NULL_HANDLE, sampler must be a valid VkSampler handle

If pAllocator is not NULL, pAllocator must be a valid pointer to a valid VkAllocationCallbacks structure

If sampler is a valid handle, it must have been created, allocated, or retrieved from device
