Difficult while acquiring LWLocks

[hariprasath nallasamy <hariprasathnallasamy@xxxxxxxxx>]

Hi all

   There is an use case, where i want some 10 LightWeight Locks and after 9.6 LW locks api's (LWLockAssign) are changed a bit and i am confused too.

 Only reference i cant get was from pg_stat_statement :(

Since GetNamedLWLockTranche method will return the base address of the specified tranche.

From pg_init

" RequestNamedLWLockTranche("Some_10_LWLocks", 10); "


For getting those locks which were requested from pg_init
" LWLockPadded *lwLockPadded = GetNamedLWLockTranche("Some_10_LWLocks");
   LWLock *lock = &(lwLockPadded[index in 0 to 9]).lock; "

Is the above code snippet a valid for requesting some 10 LWLocks?

TIA
