bionic (3) tdb_chainlock.3.gz

Provided by: libtdb-dev_1.3.15-2_amd64 bug

NAME
       tdb_chainlock - lock a group of keys tdb_chainunlock - unlock a previously locked group of keys


SYNOPSIS
       #include <tdb.h>

       int tdb_chainlock(TDB_CONTEXT *tdb, TDB_DATA key);
       void tdb_chainunlock(TDB_CONTEXT *tdb, TDB_DATA key);


DESCRIPTION
       tdb_chainlock  is a low-level function used to lock a particular key (and a number of other keys) without
       any checking: any other process attempting to perform tdb operations  on  those  keys  will  block  until
       tdb_chainunlock is called.


NOTES
       It  is  the user's responsibility to ensure that they do not deadlock the database using these functions:
       something which is impossible using the other access functions.


RETURN VALUE
       A return value of 0 indicates success and -1 indicates failure.
