Solve the following python programming problem given the following code:
def __init__(self) : 
    libc = ctypes.CDLL (ctypes.util.find_library ('c'), use_errno = True) 
    try : 
        c_splice = libc.splice 
except AttributeError : 
        self._c_splice = None 
        return 
c_loff_t_p = ctypes.POINTER (c_loff_t) 
    c_splice.argtypes = [ctypes.c_int, c_loff_t_p, ctypes.c_int, self, ctypes.c_size_t, ctypes.c_uint] 
    c_splice.restype = c_ssize_t 
    def errcheck(result, func, arguments) : 
        if (result == (- 1)) : 
            errno = ctypes.set_errno (0) 
            raise IOError (errno, ('splice: %s' % os.strerror (errno))) 
else : 
            off_in = arguments [1] 
            off_out = arguments [3] 
            return (result, (off_in.contents.value if (off_in is not None) else None), (off_out.contents.value if (off_out is not None) else None)) 
c_splice.errcheck = errcheck 
    self._c_splice = c_splice 

    
    

    Fix the buggy line: c_splice.argtypes = [ctypes.c_int, c_loff_t_p, ctypes.c_int, self, ctypes.c_size_t, ctypes.c_uint]

#Here is Python code to fix the buggy line: c_splice.

c_splice.argtypes = [ctypes.c_int, c_loff_t_p, ctypes.c_int, c_loff_t_p, ctypes.c_size_t, ctypes.c_uint]
