NAME
    cgGetConnectedToParameter - gets a connected destination parameter

SYNOPSIS
      #include <Cg/cg.h>

      CGparameter cgGetConnectedToParameter( CGparameter param,
                                             int index );

PARAMETERS
    param   The source parameter.

    index   Since there may be multiple destination (to) parameters
            connected to param, index is need to specify which one is
            returned. index must be within the range of 0 to N - 1 where N
            is the number of connected destination parameters.

RETURN VALUES
    Returns one of the destination parameters connected to param.

    Returns NULL if an error occurs.

DESCRIPTION
    Returns one of the destination parameters connected to param.
    cgGetNumConnectedToParameters should be used to determine the number of
    destination parameters connected to param.

EXAMPLES
        int nParams = cgGetNumConnectedToParameters( sourceParam );

        for ( int i=0; i < nParams; ++i )
        {
          CGparameter toParam = cgGetConnectedToParameter( sourceParam, i );
          /* Do stuff with toParam ... */
        }

ERRORS
    CG_INVALID_PARAM_HANDLE_ERROR is generated if param is not a valid
    parameter.

    CG_OUT_OF_ARRAY_BOUNDS_ERROR is generated if index is less than 0 or
    greater than or equal to the number of parameters connected to param.

HISTORY
    cgGetConnectedToParameter was introduced in Cg 1.2.
