Apple System Software (T-Z)
This chapter lists selector codes of which the meaning is documented and the first character of the selector code is in the T-Z range.
tabl (System [6.0.4])
gestaltSelectorTable?
Returns a handle to the Gestalt selector table itself.
#define gestaltSelectorTable? 'tabl' /* Gestalt Table address */
WARNING:
Although this information isn't officially confirmed, it is probably
correct. But it is likely to go away in future systems.
NOTE:
The Gestalt selector table is kept in a resizable block in the system
heap. The last item in the table is a dummy entry (INVALID), marked by
a selector OSType(MaxLongInt). (Marco Piovanelli, he also has some
snippet Pascal code to list all selectors)
With System 7.5 each item in the table now contains three parts:
the selector, an information field and a field with either a pointer
or a value. If the information field (or only bit 0) is 1, a value is
stored, otherwise a pointer to the gestalt function. (Eric-Paul Rebel)
For backward compatibility this selector probably now points to a
second table using the old format. (Rene Ros)
The Gestalt dcmd included with MacsBug 6.5.4a4 or later ignores this
selector because it makes toolbox calls that don't work in the dcmd
environment.
tbtt (System [6.0.8])
gestaltToolboxTable
Returns the base address of the Toolbox trap table.
#define gestaltToolboxTable 'tbtt' /* Toolbox trap table base */

NOTE:
Starting with Copland (abandoned Mac OS 8) VM is always on but this
selector will tell VM is off. A future selector allows to test if
the microkernel is running and thus if VM is actually used.

of zero when the table is contiguous? (Rene Ros)
