berkeley db

[Wojtek]

Hi I'm writing multiprocess server which has to gather information from
the clients and store it to berkeley db. The problem is that BerkeleyDB
adds entries to the base only if they are added from the same proces
within was created all is ok. But when I fork() it the code runs without
any error, but DB adds nothnig . How can I solve this problem.

Thank you in advance

This has nothing to do with C. Please ask in comp.unix.programmer or a
system-specific newsgroup.

Berkeley DB handles cannot be shared across a fork, each forked child
should open the DB database environment separately. (You'll almost
certainly need a database environment in the case of a multi-process
application.)
