The `_flags` and `_flags2` bitmasks are decoded to a readable string when printing the struct.
Next to setting the flags as an integer like before, you can set individual bits now and check set bits.
```
fileStr = FileStructure(null=0xdeadbeeef)
fileStr.flags = 0xfbad1807
fileStr.flags = IO_flags._IO_MAGIC | IO_flags._IO_USER_BUF | IO_flags._IO_UNBUFFERED
fileStr.flags._IO_USER_BUF = 1
```
Printing the FileStructure shows the flags in human readable form too
```
{ flags: 0xfbad0401 (_IO_USER_BUF | _IO_UNBUFFERED | _IO_MAGIC)
_IO_read_ptr: 0x0
...
```
