Open Transport Libraries

Q: I want to program with OpenTransport. What libraries should I link with?

A: Here are descriptions of each of the libraries that come with OT, and why you might need to link them.

Linking OT for PPC Code

To give you a quick start, the basic libraries to link with your application are:

OpenTransportLib
OpenTransportAppPPC.o

If you need AppleTalk services, also link with:

OpenTptAppleTalkLib
OpenTptATalkPPC.o

If you need Internet services, also link with:

OpenTptInternetLib
OpenTptInetPPC.o

The two following libraries may provide a smaller footprint if your application only deals with ports. Once you've got it working, try replacing OpenTransportLib and OpenTransportAppPPC.o with these and see if your application still links:

OpenTransportUtilLib
OpenTptUtilsAppPPC.o

The following libraries replace the OpenTransportAppPPC.o and OpenTptUtilsAppPPC.o if you are writing a stand-alone code resource, CFM fragment, or ASLM shared library:

OpenTransportExtnPPC.o
OpenTptUtilsExtnPPC.o

Linking OT for 68K Code

To give you a quick start, the basic libraries to link with your application are:

OpenTransport.o
OpenTransportApp.o

If you need AppleTalk services, also link with:

OpenTptATalk.o

If you need Internet services, also link with:

OpenTptInet.o

The following library may provide a smaller footprint if your application only deals with ports. Once you've got it working, try replacing the first library with this and see if it still links:

OpenTptUtils.o

The following library replaces the OpenTransportApp.o if you are writing a stand-alone code resource or ASLM shared library:

OpenTransportExtn.o

In addition, the following libraries are identical to their similarly named counterparts except that they are suitable for linking with MPW model near clients:

OpenTransport.n.o
OpenTransportApp.n.o
OpenTptATalk.n.o
OpenTptInet.n.o
OpenTptUtils.n.o
OpenTransportExtn.n.o
