Hi -
We have C code which writes following struct into berkeley db ("my_db.db").
struct my_info {
unsigned long int i, e;
int o;
char *f;
char *s;
};
How to read this via Python? Google search gave this code
---
$ cat pybsd2.py
from bsddb import db
fruitDB = db.DB()
fruitDB.open('my_db.db', None, db.DB_BTREE, db.DB_DIRTY_READ)
cursor = fruitDB.cursor()
rec = cursor.first()
while rec:
print rec
rec = cursor.next()
fruitDB.close()
---
While storing an entry (o=>500,f=>/home/laks/abcde,s=>OSr,i=>4668368
,e=>10000) and reading it back i get
$ python pybsd2.py
("\x10'\x00\x00\x00\x00\x00\x00",
"\xf4\x01\x00\x00\xd0;G\x00\x00\x00\x00\x00\x10'\x00\x00\x00\x00\x00\x00/home/laks/abcde\x00OSr\x00")
And this http://docs.python.org/2/library/bsddb.html says bdb module is
removed recently.
Further Searching provides modules like cpickle,ctypes,struct - not sure
which is the right approach/way to proceed.
Should we proceed with bdb module and find out how to retrive integer from
db or use others like ctypes/(c)pickle/struct etc?
Thanks for any help.
Ps : If this question already answered and discussed often, please redirect
me to that thread.
