VkBool32(3) Manual Page

VkBool32 represents boolean True and False values, since C does not have a sufficiently portable built-in boolean type:

VK_TRUE represents a boolean True (unsigned integer 1) value, and VK_FALSE a boolean False (unsigned integer 0) value.

All values returned from a Vulkan implementation in a VkBool32 will be either VK_TRUE or VK_FALSE.

Applications must not pass any other values than VK_TRUE or VK_FALSE into a Vulkan implementation where a VkBool32 is expected.
