Each of these functions allocates memory for the internal file structure and converts the filter coefficients into an internal representa- tion. PARAMETERS
Each of the functions takes the following arguments: filter Internal filter structure. flt Array of five filter coefficients: a0, a1, a2, b1, and b2. RETURN VALUES
Each of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE. ATTRIBUTES
