Cg Core Runtime API                         cgGetProgramOutput(3)



NAME
     cgGetProgramOutput - get the program's output

SYNOPSIS
       #include 

       CGenum cgGetProgramOutput( CGprogram program );


PARAMETERS
     program A program handle.

RETURN VALUES
     Returns a program output enumerant.  If the program is a
     vertex or fragment program, it returns CGVERTEX or
     CGFRAGMENT, respectively.  For geometry programs the output
     is one of: CGPOINTOUT, CGLINEOUT, or CGTRIANGLEOUT.

     Returns CGUNKNOWN if the output is unknown.

DESCRIPTION
     cgGetProgramOutput returns the program output enumerant.

     For geometry programs, an input must be specified but not an
     output because of implicit output defaults.  For example, if
     either "TRIANGLE" or "TRIANGLEADJ" is specified as an input
     without an explicit output in the shader source, then
     cgGetProgramOutput will return CGTRIANGLEOUT.

EXAMPLES
       void printProgramOutput(CGprogram program)
       {
         char * output = NUL;
         switch(cgGetProgramOutput(program))
         {
           case CGPOINTOUT:
               output = "point";
               break;
           case CGLINEOUT:
               output = "line";
               break;
           case CGTRIANGLEOUT:
               output = "triangle";
               break;
           default:
               output = "unknown";
               break;
         }
         printf("Program outputs %s.\n", output);
       }
