[C++-sig] [Py++] ctypes generator ignores bit fields

[Nikolaus Rath]

Hello,

The ctypes code generator translates the struct

struct fuse_file_info {
        int flags;
        unsigned long fh_old;
        int writepage;
        unsigned int direct_io : 1;
        unsigned int keep_cache : 1;
        unsigned int flush : 1;
        unsigned int padding : 29;
        uint64_t fh;
        uint64_t lock_owner;
};

into

fuse_file_info._fields_ = [ #class fuse_file_info
    ("flags", ctypes.c_int),
    ("fh_old", ctypes.c_ulong),
    ("writepage", ctypes.c_int),
    ("direct_io", ctypes.c_uint),
    ("keep_cache", ctypes.c_uint),
    ("flush", ctypes.c_uint),
    ("padding", ctypes.c_uint),
    ("fh", ctypes.c_ulonglong),
    ("lock_owner", ctypes.c_ulonglong),
]

but this is wrong, the correct translation is:

fuse_file_info._fields_ = [
        ('flags', ctypes.c_int),
        ('fh_old', ctypes.c_ulong),
        ('writepage', ctypes.c_int),
        ('direct_io', ctypes.c_uint, 1),
        ('keep_cache', ctypes.c_uint, 1),
        ('flush', ctypes.c_uint, 1),
        ('padding', ctypes.c_uint, 29),
        ('fh', ctypes.c_uint64),
        ('lock_owner', ctypes.c_uint64)]

Best,

   -Nikolaus
