Find out name of graphics card driver in a C++ OpenGL program

I'm searching for a way to find out the name of the currently used graphics card driver inside a C++ OpenGL program. At best would be a platform-independent way (Linux and Windows). The only thing I could find was this but that's a shell solution and might even vary along different distributions (and still, Windows would be a problem).

I already looked at glGetString() with the GL_VENDOR parameter, however that outputs the vendor of the graphics card itself, not the driver. I couldn't find any options/functions that give me what I want.

Is there an easy solution to this problem?

Try these:

const GLubyte* vendor = glGetString(GL_VENDOR); 
const GLubyte* renderer = glGetString(GL_RENDERER); 
const GLubyte* version = glGetString(GL_VERSION);

This is probably not the ultimate answer, but it might help you. You can work out the driver name and version combining both the lsmod and modinfo commands, under Linux.

For example, my lsmods returns the following:

$ lsmod 
Module                  Size  Used by                
autofs                  28170 2  
binfmt_misc             7984  1  
vboxnetadp              5267  0  
vboxnetflt             14966  0  
vboxdrv              1793592  2 vboxnetadp,vboxnetflt  
snd_hda_codec_nvhdmi   15451  1 
snd_hda_codec_analog   80317  1  
usbhid                 42030  0  hid
nvidia              11263394  54

from which I know that nvidia refers to the graphics card.

I can then run modinfo nvidia and I get

filename:       /lib/modules/2.6.35-32-generic/kernel/drivers/video/nvidia.ko
alias:          char-major-195-*
version:        304.54
supported:      external
license:        NVIDIA
alias:          pci:v000010DEd00000E00sv*sd*bc04sc80i00*
alias:          pci:v000010DEd00000AA3sv*sd*bc0Bsc40i00*
alias:          pci:v000010DEd*sv*sd*bc03sc02i00*
alias:          pci:v000010DEd*sv*sd*bc03sc00i00*
depends:

And I can extract the driver version etc...

I know this is neither a straight forward solution nor multiplatform, but you might work out an script that extracts driver name and versions if you guess that most of names will be nvidia, ati, intel etc... by grep / awk the output of lsmod.
