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.
