NAME
    cgGetParameterValueic - get the value of any numeric parameter

SYNOPSIS
      #include <Cg/cg.h>

      int cgGetParameterValueic( CGparameter param, 
                                 int nelements,
                                 int * v );

PARAMETERS
    param   The parameter whose value will be retrieved.

    nelements
            The number of elements in array v.

    v       Destination buffer into which the parameter values will be
            written.

RETURN VALUES
    Returns the total number of values written to v.

DESCRIPTION
    cgGetParameterValueic allows the application to get the value(s) from
    any numeric parameter or parameter array. The value(s) are returned as
    ints in v.

    The given parameter must be a scalar, vector, matrix, or a (possibly
    multidimensional) array of scalars, vectors, or matrices.

    Any matrices referenced by param will be copied in column-major order.

    The size of v is passed as nelements. If v is smaller than the total
    number of values in the given source parameter, CG_NOT_ENOUGH_DATA_ERROR
    is generated.

    The total number of values in a parameter, ntotal, may be computed as
    follow:

                int nrows = cgGetParameterRows(param);
                int ncols = cgGetParameterColumns(param);
                int asize = cgGetArrayTotalSize(param);
                int ntotal = nrows*ncols;
                if (asize > 0) ntotal *= asize;

EXAMPLES
    *to-be-written*

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

    CG_INVALID_POINTER_ERROR is generated if v is NULL.

    CG_NOT_ENOUGH_DATA_ERROR is generated if nelements is less than the
    total size of param.

    CG_NON_NUMERIC_PARAMETER_ERROR is generated if param is of a non-numeric
    type.

HISTORY
    cgGetParameterValueic was introduced in Cg 1.4.
