  <P
>   <SPAN
CLASS="APPLICATION"
>libpq++</SPAN
> is the C++ API to 
   <SPAN
CLASS="PRODUCTNAME"
>PostgreSQL</SPAN
>.
   <SPAN
CLASS="APPLICATION"
>libpq++</SPAN
>  is a set of classes that allow
   client programs to connect to the 
   <SPAN
CLASS="PRODUCTNAME"
>PostgreSQL</SPAN
> backend server. These connections
   come in two forms: a database class and a large object class.
  </P
>

  <P
>   The database class is intended for manipulating a database. You can
   send all sorts of SQL queries and commands to the <SPAN
CLASS="PRODUCTNAME"
>PostgreSQL</SPAN
> 
   backend server and retrieve the responses of the server.
  </P
>

  <P
>   The large object class is intended for manipulating a large object
   in a database. Although a large object instance can send normal
   queries to the <SPAN
CLASS="PRODUCTNAME"
>PostgreSQL</SPAN
> backend server 
   it is only intended for simple
   queries that do not return any data. A large object should be seen
   as a file stream. In the future it should behave much like the C++ file
   streams
   <TT
CLASS="LITERAL"
>cin</TT
>,
   <TT
CLASS="LITERAL"
>cout</TT
>
   and
   <TT
CLASS="LITERAL"
>cerr</TT
>.
  </P
>

  <P
>   This chapter is based on the documentation for the
   <SPAN
CLASS="APPLICATION"
>libpq</SPAN
> C library (see libpq).  There
   are several examples of <SPAN
CLASS="APPLICATION"
>libpq++</SPAN
>
   applications in
   <TT
CLASS="FILENAME"
>src/interfaces/libpq++/examples</TT
> in the source
   distribution.
