glGetTexGen returns in params selected parameters of a texture coordinate generation function that was specified using glTexGen. coord names one of the (s, t, r, q) texture coordinates, using the symbolic constant GL_S, GL_T, GL_R, or GL_Q.
pname specifies one of three symbolic names:
If an error is generated, no change is made to the contents of params.
When the GL_ARB_multitexture extension is supported, glGetTexGen returns the texture coordinate generation parameters for the active texture unit.
