Parameters
param
A token selecting which parameter the function should return (see table 3.2).

Return values
The function returns different parameters depending on the value of param. Table 3.2 lists valid param
values, and their corresponding return values.

Description
The function is used for acquiring various properties of an opened window.

Notes
GLFW_ACCELERATED is only supported under Windows. Other systems will always return
GL_TRUE. Under Windows, GLFW_ACCELERATED means that the OpenGL™ renderer is a 3rd
party renderer, rather than the fallback Microsoft software OpenGL™ renderer. In other words, it is
not a real guarantee that the OpenGL™ renderer is actually hardware accelerated.
