Programming guideline of WinDom

From WinDom version 1.00 (November 2000)

Some macros and functions had changed

remplace 'min()' by 'MIN()'
remplace 'max()' by 'MAX()'
remplace 'is_in()' by 'IS_IN()'
remplace 'STR2INT()' by 'ADR()'
remplace 'ExecGemApp()' by 'ShelWrite()'
remplace 'rect_set()' by 'rc_set()'
remplace 'set_clip()' by 'rc_clip_on()'
remplace 'clip_off()' by 'rc_clip_off()'

Pointers parameters in some function with Gcc 32

emcapsule pointer arguments with ADR() macro in ApplWrite() function. For example,
```
     		strcpy( app.file, file_to_open);
     		ApplWrite( apid, VA_START, app.pipe);
```
is remplaced by :
```
     		strcpy( app.file, file_to_open);
     		ApplWrite( apid, VA_START, ADR(app.pipe));
```
The variable app.file is a 256-character buffer reserved in global memory by ApplInit() and devoted to GEM communication with other application (very important with MiNT memory protection mode).
The previous remark addresses the WindSet() function. Use the macro function ADR() or WindSetPtr() and WindGetPtr(). functions.

New macro SET_BIT

The function set_bit() is remplaced by the macro function SET_BIT(). The main advantage is the macro uses untyped variable. The first parameter of set_bit() was a pointer but in SET_BIT() it is not a pointer. Let's see an example. Remplace :

	int val;
	set_bit( &val, 0x100, TRUE);

by :

	int val;
	SET_BIT( val, 0x100, TRUE);

List of functions with new prototype
Many functions have new prototype (INT16 type instead of int type). For Pure C users, there is no change. Functions concerned are:

AvWaitfor(), ObjcEdit(), WindGet(), ApplWrite(), WindCalc(), give_iconifyxywh(), vqt_extname(), RsrcFixCicon(), FrameCalc(), GrectCenter().
