vkDestroySampler

vkDestroySampler is a Vulkan API function used to release resources associated with a VkSampler object. When a VkSampler object is no longer needed, calling this function ensures that the associated memory and other system resources are deallocated and made available for reuse. This is crucial for preventing memory leaks and maintaining the efficient operation of a Vulkan application.

The function takes two arguments: a VkDevice, representing the logical device with which the sampler was created, and a VkSampler, the handle to the sampler object to be destroyed. It is important to ensure that the VkSampler being destroyed is not currently in use by any active Vulkan commands or operations. Destroying a sampler that is still in use can lead to undefined behavior and application crashes.

The caller is responsible for managing the lifetime of VkSampler objects. Typically, a sampler is created using vkCreateSampler and should be explicitly destroyed using vkDestroySampler when it is no longer required. Failure to destroy samplers can result in a gradual depletion of system resources, impacting performance and potentially causing the application to terminate. This function is part of the Vulkan resource management system, emphasizing the explicit control developers have over resource allocation and deallocation.
