NAME
    cgGetFirstLeafParameter - get the first leaf parameter in a program

SYNOPSIS
      #include <Cg/cg.h>

      CGparameter cgGetFirstLeafParameter( CGprogram program,
                                           CGenum name_space );

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

    name_space
            Specifies the namespace of the parameter to iterate through.
            Currently CG_PROGRAM and CG_GLOBAL are supported.

RETURN VALUES
    cgGetFirstLeafParameter returns a the first leaf CGparameter object in
    program. NULL is returned 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 the
    cgGetNextLeafParameter manpage for more information.

EXAMPLES
    *to-be-written*

ERRORS
    CG_INVALID_PROGRAM_HANDLE_ERROR is generated if program does not refer
    to a valid program.

    CG_INVALID_ENUMERANT_ERROR is generated if name_space is not CG_PROGRAM
    or CG_GLOBAL.

HISTORY
    cgGetFirstLeafParameter was introduced in Cg 1.1.
