Request for example using pqconnectstart,pqconnectpoll part.

2021-02-04 Thread Om Prakash Jaiswal
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.
