Thread: how to access backend pid from libpq ?

I was unable to find the way to access the backend pid from libpq

It is probably saved somewhere as part of BackendKeyData message
but there seems to be no function to access it ?

I'm using a temporary solution (my own 'C' function) but I'd like 
to use the info already received.

Ok, I found it from the libpq source: PQbackendPID

I still think it could be documented ;)

extern int      PQbackendPID(const PGconn *conn);

Strange how one starts to find things when you are told they are there
;)

I could have sworn that doing grep PQbackendPID over libpq.sgml in fresh 
REL7_0_PATCHES returned zero rows before I posted .

Sorry for panicing.
