       void GLAPIENTRY glGetTexEnviv( GLenum target,
                                      GLenum pname,
                                      GLint *params )

PARAMETERS
       target  Specifies a texture environment.  Must be GL_TEXTURE_ENV.

       pname   Specifies  the symbolic name of a texture environment parameter.
               Accepted      values      are      GL_TEXTURE_ENV_MODE       and
               GL_TEXTURE_ENV_COLOR.

       params  Returns the requested data.

DESCRIPTION
       glGetTexEnv  returns  in params selected values of a texture environment
       that was specified with glTexEnv.  target specifies a  texture  environ‐
       ment.  Currently, only one texture environment is defined and supported:
       GL_TEXTURE_ENV.

       pname names a specific texture environment parameter, as follows:

       GL_TEXTURE_ENV_MODE
                 params returns the single-valued texture environment  mode,  a
                 symbolic constant. The initial value is GL_MODULATE.

       GL_TEXTURE_ENV_COLOR
                 params  returns four integer or floating-point values that are
                 the texture  environment  color.   Integer  values,  when  re‐
                 quested,  are linearly mapped from the internal floating-point
                 representation such that 1.0 maps to the most positive  repre‐
                 sentable  integer,  and  -1.0 maps to the most negative repre‐
                 sentable integer. The initial value is (0, 0, 0, 0).

NOTES
       If an error is generated, no change is made to the contents of params.

       When the GL_ARB_multitexture extension is supported, glGetTexEnv returns
       the texture environment parameters for the active texture unit.

ERRORS
       GL_INVALID_ENUM  is  generated  if  target  or  pname is not an accepted
       value.

       GL_INVALID_OPERATION is generated if glGetTexEnv is executed between the
       execution of glBegin and the corresponding execution of glEnd.
