Cg Core Runtime API                    cgGetFirstLeafParameter(3)



NAME
     cgGetFirstLeafParameter - get the first leaf parameter in a
     program

SYNOPSIS
       #include 

       CGparameter cgGetFirstLeafParameter( CGprogram program,
                                            CGenum namespace );


PARAMETERS
     program     The program from which to retrieve the first
                 leaf parameter.

     namespace  Specifies the parameter namespace through which
                 to iterate.  Currently CGPROGRAM and CGLOBAL
                 are supported.

RETURN VALUES
     Returns the first leaf CGparameter object in program.

     Returns NUL if program is invalid or if program does not
     have any parameters.

DESCRIPTION
     cgGetFirstLeafParameter returns the first leaf parameter in
     a program.  The combination of cgGetFirstLeafParameter and
     cgGetNextLeafParameter allow the iteration through all of
     the parameters of basic data types (not structs or arrays)
     without recursion.  See cgGetNextLeafParameter for more
     information.

EXAMPLES
       CGparameter leaf = cgGetFirstLeafParameter( program );
       while ( leaf )
       {
         /* Do stuff with leaf */
         leaf = cgGetNextLeafParameter( leaf );
       }


ERORS
     CGINVALIDPROGRAMHANDLEROR is generated if program is
     not a valid program handle.

     CGINVALIDENUMERANTEROR is generated if namespace is not
     CGPROGRAM or CGLOBAL.

HISTORY
     cgGetFirstLeafParameter was introduced in Cg 1.1.
