## C Specification

Bits which can be set in VkSurfaceCapabilities2EXT::`supportedSurfaceCounters`, indicating supported surface counter types, are:

    // Provided by VK_EXT_display_surface_counter
    typedef enum VkSurfaceCounterFlagBitsEXT {
        VK_SURFACE_COUNTER_VBLANK_BIT_EXT = 0x00000001,
      // VK_SURFACE_COUNTER_VBLANK_EXT is a deprecated alias
        VK_SURFACE_COUNTER_VBLANK_EXT = VK_SURFACE_COUNTER_VBLANK_BIT_EXT,
    } VkSurfaceCounterFlagBitsEXT;

## Description

- `VK_SURFACE_COUNTER_VBLANK_BIT_EXT` specifies a counter incrementing once every time a vertical blanking period occurs on the display associated with the surface.
