For d3d9 that would probably be IDirect3D9::CheckDeviceFormat(),
IDirect3D9::EnumAdapterModes(), IDirect3D9::GetAdapterIdentifier() and
IDirect3D9::GetDeviceCaps(). Ddraw and d3d8 should have similar
methods, I'm not completely sure about dxgi/d3d10.
For OpenGL there's DescribePixelFormat(), and glGetString() with
various constants like GLRENDERER, GL_VENDOR, GL_VERSION and
GL_EXTENSIONS. Limits are usually retrieved with glGetIntegerv() or
glGetFloatv() and an appropriate constant.

I don't know, but if I were to guess I'd say it probably doesn't get
that information from d3d, but from gdi32 or winex11.drv.
