How to use the send2trash.plat_win.SHFILEOPSTRUCTW function in Send2Trash

def send2trash(path):
    if not isinstance(path, text_type):
        path = text_type(path, 'mbcs')
    if not op.isabs(path):
        path = op.abspath(path)

    fileop.wFunc = FO_DELETE
    # FIX: https://github.com/hsoft/send2trash/issues/17
    # Starting in python 3.6.3 it is no longer possible to use:
    # LPCWSTR(path + '\0') directly as embedded null characters are no longer
    # allowed in strings
    # Workaround
    #  - create buffer of c_wchar[] (LPCWSTR is based on this type)
    #  - buffer is two c_wchar characters longer (double null terminator)
    #  - cast the address of the buffer to a LPCWSTR
    # NOTE: based on how python allocates memory for these types they should
    # always be zero, if this is ever not true we can go back to explicitly
    # setting the last two characters to null using buffer[index] = '\0'.
    buffer = create_unicode_buffer(path, len(path)+2)
    fileop.pFrom = LPCWSTR(addressof(buffer))
    fileop.pTo = None
