connection problem

["Tuğberk Kara" <tugberkkara(at)gmail(dot)com>]

I have a postgresql installed on a remote machine. I want to connect to it with libpq but the connection is not successful.

I have this piece of code for connection in my c file:

 

PGconn *conn=NULL;

char  *conn_str="hostaddr=172.16.11.2 port=5432 dbname=postgres user=postgres password=654321 reqiressl=0";

conn=PGconnectStart(conn_str);

if(PGstatus(conn)=CONNECTION_BAD){

 

  PGerrorMessage(conn);

}

else{

 

printf("connected");

 

}

 

But I can not connect. It exits from the program. I tried also PGconnectdb but it also did not connect to the databse. But I can connect to it thorough pgAdmin with the same credentials. Can you help me please urgently!'!!!
