Hi, I have 2 questions regarding the asynchronous C api (I am using vers. 8.4): 1) To make a connection in non-blocking manner the api provides PGconn *PQconnectStart(const char *conninfo) function. The parameters are passed in 'conninfo' variable which is a string so I have to use sprintf() to put the parameters into this string. Is there another function to connect asynchronously that would be similar to PQsetdbLogin so it would accept the host/port/user/password parameters directly as argument to the function? I want to avoid to use sprintf() 2) Will this code produce a valid non-blocking connection ? db_globals=PQsetdbLogin(DT_DBHOST,DT_DBPORT,NULL,NULL,"global",DT_DBUSER,DT_DBPASS); if (PQstatus(db_globals) != CONNECTION_OK) { fprintf(stderr, "Connection to database failed: %s", PQerrorMessage(db_globals)); PQfinish(db_globals); exit(1); } if (PQsetnonblocking(db_globals, int arg)!=1) { printf("can't set global connection to non blocking mode\n"); exit(1); } Will appreciate any help Nulik -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
