Обсуждение: Request for example using pqconnectstart,pqconnectpoll part.
Hi,
Please provide a sample example using pqconnectstart , pqconnectpoll to make a asynchronous connection and executing a query for client application in C.
It is part of
libpq - C Library.
I am able to do query using
PQconnectdb and PQexec.I have also used
PQconnectdb and PQsendQuery. PQconnectdb is blocking call, now I want to replace PQconnectdb with non blocking connection pqconnectstart and pqconnectpoll.Please provide an example.
Thanks in advance.

I used it in https://github.com/laurenz/pgreplay/blob/master/database.c#L404 but it certainly is not the most concise example. Yours, Laurenz Albe -- Cybertec | https://www.cybertec-postgresql.com
