As far as I recall you can call SQLGetInfo with a NULL InfoValuePtr but a valid
StringLengthPtr. This then returns the size of the buffer you would need to get
all the data back.
e.g.
if (SQL_SUCCEEDED(SQLGetInfo(hdbc, SQL_KEYWORDS, NULL, 0, &sqlsmallint))) {
SQLCHAR buf;
buf = malloc(sqlsmallint + 1);
SQLGetInfo(hdbc, SQL_KEYWORDS, buf, sqlsmallint + 1, *sqlsmallint);
/* copy buf somewhere */
free(buf);
}
