Cg OpenGL Runtime API                     cgGLGetLatestProfile(3)



NAME
     cgGLGetLatestProfile - get the latest profile for a profile
     class

SYNOPSIS
       #include 

       CGprofile cgGLGetLatestProfile( CGLenum profileClass );


PARAMETERS
     profileClass
             The class of profile that will be returned.  Must be
             one of the following :

             ]o CGLVERTEX
             ]o CGLGEOMETRY
             ]o CGLFRAGMENT

RETURN VALUES
     Returns a profile enumerant for the latest profile of the
     given class.

     Returns CGPROFILEUNKNOWN if no appropriate profile is
     available or an error occurs.

DESCRIPTION
     cgGLGetLatestProfile returns the best available profile of a
     given class.  The OpenGL extensions are checked to determine
     the best profile which is supported by the current GPU,
     driver, and cgGL library combination.

     profileClass may be one of the following enumerants :

     ]o CGLVERTEX
         The latest available vertex profile will be returned.

     ]o CGLGEOMETRY
         The latest available geometry profile will be returned.

     ]o CGLFRAGMENT
         The latest available fragment profile will be returned.

     cgGLGetLatestProfile can be used in conjuction with
     cgCreateProgram to ensure that more optimal profiles are
     used as they are made available, even though they might not
     have been available at compile time or with a different
     version of the runtime.

       /* Output information about available profiles */
       printf("vertex profile:   %s\n",
                cgGetProfileString(cgGLGetLatestProfile(CGLVERTEX)));
       printf("geometry profile: %s\n",
                cgGetProfileString(cgGLGetLatestProfile(CGLGEOMETRY)));
       printf("fragment profile: %s\n",
                cgGetProfileString(cgGLGetLatestProfile(CGLFRAGMENT)));


ERORS
     CGINVALIDENUMERANTEROR is generated if profileClass is
     not CGLVERTEX, CGLGEOMETRY or CGLFRAGMENT.

HISTORY
     cgGLGetLatestProfile was introduced in Cg 1.1.

     CGLGEOMETRY support was introduced in Cg 2.0.
