Here is a copy of the subroutine I use. I'm pretty sure it worked fine
with 6.4.2 and the ecpg that came with it. The obstrdup() is a simple
string copy function, obstrappend appends the second string arg to the
first. You should be able to get rid of them easily, if not I'll send you
those as well. Hope this helps.
int
db_connect(char *username, char *password, char *host)
{
exec sql begin declare section;
char *xpassword;
char *xusername;
char *xhost;
exec sql end declare section;
assert (username != NULL);
assert (password != NULL);
xpassword = obstrdup(password);
xusername = obstrdup(username);
if (host)
{
xhost = obstrdup("tcp:postgresql://");
xhost = obstrappend(xhost,host);
xhost = obstrappend(xhost,"/obe");
} else {
xhost = obstrdup("tcp:postgresql://127.0.0.1/obe");
}
/* <tcp|unix>:postgresql://server[:port][/dbname][?options] */
EXEC SQL CONNECT TO :xhost USER :xusername IDENTIFIED BY :xpassword;
return 0;
}
