default_vfs_ops.open - flag param?

[troutb at abclabs.com]

Can some clue me in no how this param is used.

I've seen values like 0, 65, 193.  Looks like bit wise ...

but I can't seem to find the coresponding bit values and there MEANING.

if this is only for O_CREAT, O_WRONLY, O_EXCLU, O_RDWR

then a bit of 128 in a value like 193 seems a litte bit more than requied

is this used to store other information ...?

I have poured throught the online docs ( doxygen ... include fils ... etc ),
but can't seem to put 2 and 2 together


please help me
