GLGET(3G)							     GLGET(3G)

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
       glGetIntegerv 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.
