NAME
tdb_chainlock - lock a group of keys tdb_chainunlock - unlock a previously locked group of keysSYNOPSIS
#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.AUTHORS
