Returns whether the Vulkan loader and an ICD have been found.
This function returns whether the Vulkan loader and any minimally functional ICD have been found.
The availability of a Vulkan loader and even an ICD does not by itself guarantee that surface creation or even instance creation is possible. For example, on Fermi systems Nvidia will install an ICD that provides no actual Vulkan support. Call @ref glfwGetRequiredInstanceExtensions to check whether the extensions necessary for Vulkan surface creation are available and @ref glfwGetPhysicalDevicePresentationSupport to check whether a queue family of a physical device supports image presentation.
