module WindowHint : sig ... end

Window hints. Use with setWindowHint like this:

module WindowAttribute : sig ... end

Windows attributes. Use with getWindowAttrib in a similar manner as with window hints.

  5. blue_bits : int;
  6. refresh_rate : int;
}

Video mode description as returned by getVideoMode(s).

type monitor
type window
type cursor
module GammaRamp : sig ... end

GammaRamp module. Describes the gamma ramp for a monitor.

type image = {
  1. width : int;
  2. height : int;
  3. pixels : bytes;
}

Image data for creating custom cursors.

Module functions. These are mostly identical to their original GLFW counterparts.

There are no bindings for the glfwSetWindowUserPointer and glfwGetWindowUserPointer functions because you would have to use unsafe features to set the correct type for your data. If you need to make user data accessible inside a callback you can instead capture it in a closure and use that closure as your callback function.

There is no binding for the glfwGetProcAddress function because it would basicaly require to write an entire OpenGL wrapper to make the functions returned by GLFW usable from OCaml. Incidentaly the glfwExtensionSupported function is not provided either. There are numerous OpenGL bindings available for OCaml that you can use instead.

The Vulkan related functions are not supported as of now but we might look into it at some point.
