Cg Core Runtime API                          cgGetProgramInput(3)



NAME
     cgGetProgramInput - get the program's input

SYNOPSIS
       #include 

       CGenum cgGetProgramInput( CGprogram program );


PARAMETERS
     program A program handle.

RETURN VALUES
     Returns a program input enumerant.  If the program is a
     vertex or fragment program, it returns CGVERTEX or
     CGFRAGMENT, respectively.  For geometry programs the input
     is one of: CGPOINT, CGLINE, CGLINEADJ, CGTRIANGLE, or
     CGTRIANGLEADJ.

     Returns CGUNKNOWN if the input is unknown.

DESCRIPTION
     cgGetProgramInput returns the program input enumerant.
