vkDestroyPipelineCache

vkDestroyPipelineCache is a function in the Vulkan API, a low-level graphics and compute API. It is used to destroy a previously created pipeline cache object. A pipeline cache in Vulkan is an object that stores pipeline creation parameters and compiled pipeline code, which can be reused to speed up the creation of similar pipelines in the future.

The function takes two parameters: the first is a handle to the logical device that was used to create the pipeline cache, and the second is the handle to the pipeline cache object itself. The function returns void, meaning it does not provide any direct feedback on whether the destruction was successful.

Before calling vkDestroyPipelineCache, it is important to ensure that the pipeline cache is no longer in use by any command buffers or other Vulkan objects. Failure to do so can result in undefined behavior. Additionally, the pipeline cache object should not be destroyed while it is still being used by the GPU, as this can lead to synchronization issues.

After calling vkDestroyPipelineCache, the pipeline cache object is invalid and should not be used again. Any attempts to use an invalid pipeline cache object will result in a Vulkan validation error. It is also important to note that destroying a pipeline cache does not affect the pipelines that were created using it; those pipelines will continue to function as normal.

In summary, vkDestroyPipelineCache is a Vulkan function used to destroy a pipeline cache object. It is important to ensure that the pipeline cache is no longer in use before calling this function to avoid synchronization issues and undefined behavior.
