Main contains most of the code, including the MPW libraries, and the main program. Initialize contains code that is only used once, during startup, and can be unloaded after the program starts. %A5Init is automatically created by the Linker to initialize globals for the MPW libraries and is unloaded right away. */ /* SetPort strategy: Toolbox routines do not change the current port. In spite of this, in this program we use a strategy of calling SetPort whenever we want to draw or make calls which depend on the current port. This makes us less vulnerable to bugs in other software which might alter the current port (such as the bug (feature?) in many desk accessories which change the port on OpenDeskAcc). Hopefully, this also makes the routines from this program more self-contained, since they don't depend on the current port setting. */ /* Clipboard strategy: This program does not maintain a private scrap. Whenever a cut, copy, or paste occurs, we import/export from the public scrap to TextEdit's scrap right away, using the TEToScrap and TEFromScrap routines. If we did use a private scrap, the import/export would be in the activate/deactivate event and suspend/resume event routines. */ #define AUX /* A/UX is case sensitive, so use correct case for include file names */ #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include "MacFontUI.h" /* bring in all the #defines for MacFontUI */ #include #include #include #include #include #include #include #include #include "FS.h" #include "FSproto.h" #include "servermd.h" /* A/UX C understands neither #pragma, nor segments, so define pragma to * something harmless. */ #ifdef AUX #define pragma undef #endif /* A/UX Hybrid apps need to exit through the libc routine. */ #define ExitToShell() exit(0) /* A DocumentRecord contains the WindowRecord for one of our document windows, as well as the TEHandle for the text we are editing.

If a desk accessory owned two windows, it would close both those windows when CloseDeskAcc was called. When DoCloseBehind got around to calling DoCloseWindow for that other window that was already closed, things would go very poorly.
