Description

This module corresponds to parts of section 6.1.11 (Pointer and String Queries) of the OpenGL 2.1 specs.

Synopsis

- vendor :: GettableStateVar String
- renderer :: GettableStateVar String
- glVersion :: GettableStateVar String
- glExtensions :: GettableStateVar [String]
- shadingLanguageVersion :: GettableStateVar String
- majorMinor :: GettableStateVar String -> GettableStateVar (Int, Int)

# Documentation

vendor :: GettableStateVar String

renderer :: GettableStateVar String

glVersion :: GettableStateVar String

glExtensions :: GettableStateVar [String]

shadingLanguageVersion :: GettableStateVar String

majorMinor :: GettableStateVar String -> GettableStateVar (Int, Int)

A utility function to be used with e.g. `glVersion` or `shadingLanguageVersion`, transforming a variable containing a string of the form major.minor[optional rest] into a variable containing a numeric major/minor version. If the string is malformed, which should never happen with a sane OpenGL implementation, it is transformed to `(-1,-1)`.
