NAME
       glGetBooleanv,  glGetDoublev,  glGetFloatv,  glGetIntegerv - return the
       value or values of a selected parameter

C SPECIFICATION
       void glGetBooleanv( GLenum pname,
			   GLboolean *params )

C SPECIFICATION
       void glGetDoublev( GLenum pname,
			  GLdouble *params )

C SPECIFICATION
       void glGetFloatv( GLenum pname,
			 GLfloat *params )

C SPECIFICATION
       void glGetIntegerv( GLenum pname,
			   GLint *params )

PARAMETERS
       pname   Specifies the parameter value to	 be  returned.	 The  symbolic
	       constants in the list below are accepted.

       params  Returns the value or values of the specified parameter.

DESCRIPTION
       These  four  commands  return  values for simple state variables in GL.
       pname is a symbolic  constant  indicating  the  state  variable	to  be
       returned,  and params is a pointer to an array of the indicated type in
       which to place the returned data.

       Type conversion is performed if params has a different  type  than  the
       state  variable	value  being requested.	 If glGetBooleanv is called, a
       floating-point (or integer) value is converted to GL_FALSE if and  only
       if it is 0.0 (or 0).  Otherwise, it is converted to GL_TRUE.  If glGet‐
       Integerv is called, boolean values are returned as GL_TRUE or GL_FALSE,
       and  most  floating-point  values  are  rounded	to the nearest integer
       value. Floating-point colors and normals, however, are returned with  a
       linear mapping that maps 1.0 to the most positive representable integer
       value, and -1.0 to the most negative representable integer  value.   If
       glGetFloatv  or	glGetDoublev is called, boolean values are returned as
       GL_TRUE or GL_FALSE, and integer values are converted to floating-point
       values.
