* Resource Tracking stuff... *
************************************************************************
* *
* There are a few things in arp.library that are only directly *
* acessable from assembler. The glue routines provided by us for *
* all 'C' compilers use the following conventions to make these *
* available to C programs. The glue for other language's should use *
* as similar a mechanism as possible, so that no matter what language *
* or compiler we speak, when talk about arp, we will know what the *
* other guy is saying. *
* *
* Here are the cases: *
* *
* Tracker calls... *
* These calls return the Tracker pointer as a secondary *
* result in the register A1. For C, there is no clean *
* way to return more than one result so the tracker *
* pointer is returned in IoErr(). For ease of use, *
* there is a define that typecasts IoErr() to the correct *
* pointer type. This is called LastTracker and should *
* be source compatible with the earlier method of storing *
* the secondary result. *
* *
* GetTracker() - *
* Syntax is a bit different for C than the assembly call *
* The C syntax is GetTracker(ID). The binding routines *
* will store the ID into the tracker on return. Also, *
* in an effort to remain consistant, the tracker will *
* also be stored in LastTracker. *
* *
* In cases where you have allocated a tracker before you have obtained *
* a resource (usually the most efficient method), and the resource has *
* not been obtained, you will need to clear the tracker id. The macro *
* CLEAR_ID() has been provided for that purpose. It expects a pointer *
* to a DefaultTracker sort of struct. *
************************************************************************
*/

* IoErr() and thus causing LastTracker to give you trash... *
* *
* N O T E ! You MUST! have IoErr() defined as LONG to use LastTracker *

* *
* NOTE: The two user variables mentioned in an earlier version don't *
