*
* PIFMGR.C
* Main module for PIFMGR.DLL
*
* History:
* Created 31-Jul-1992 3:30pm by Jeff Parsons
*
* Exported Program Information File (PIF) Manager services:
*
* PifMgr_OpenProperties()
* Give it the name of an DOS application (com, exe, or bat),
* and it will open the PIF associated with that application
* and return a "handle" to the app's "properties". Use this
* handle when calling any of the other "properties" services (ie,
* Get, Set, and Close).
*
* If no PIF exists, it will still allocate a PIF data block
* in memory and initialize it, either with data from _DEFAULT.PIF
* or its internal defaults. It will also construct the PIF name
* it was looking for but couldn')t find and save that in its internal
* PIF data structure, so that if PifMgr_SetProperties is ever called, the
* data can be saved to disk.
*
* PifMgr_GetProperties()
* Returns the specified block of data from the associated PIF.
* If it is a "named" block, it must be the name of a linked
* extension inside the PIF, which can be any predefined name
* (eg, "WINDOWS 386 3.0") or the name of your own block. You can
* create your own named data blocks using the PifMgr_SetProperties()
* service. "Named" data can also be thought of as "raw" data,
* because it is returned to the caller as-is -- without translation.
*
* The size of a named block can be determined by calling
* PifMgr_GetProperties with a size of zero; no data is copied, but the size
* of the requested block is returned (0 if not found).
*
* All named blocks can be enumerated by passing NULL for the name,
* a pointer to a 16-byte buffer for the requested block name, and a
* 0-based block index in the size parameter. The size returned
* is the size of the block (0 if none).
*
* If an unnamed property block is requested (ie, the selector of
* the name parameter is NULL, and the offset is a property group
* ordinal), then the associated structure is returned. For example,
* PifMgr_GetProperties(GROUP_TSK) returns a predefined structure (see
* PROPTSK in PIF.H) containing all the tasking-related information,
* in a format that is PIF-independent. This is a valuable service,
* because it relieves callers from having to cope with PIFs
* containing a wide variety of sections (known as PIF extensions),
* only one of which is required. Think of this as "cooked" data.
*
* A third variation is raw read/write of the entire PIF data block,
* if lpszGroup is NULL. This must be used with extreme caution, and
* will only be allowed if the properties were opened with the
* OPENPROPS_RAWIO flag specified.
*
* PifMgr_SetProperties()
* This is pretty much the opposite of PifMgr_GetProperties, except that it
* also takes a flags parameter that can specify that the changes
* be made immediately, or deferred to PifMgr_CloseProperties.
*
* PifMgr_CloseProperties()
* Flushes any dirty PIF data in memory, and frees the local heap
* storage.

/**************************************************************************
*
* OVERVIEW OF INI FILE USAGE
*
*
* SYSTEM.INI
*
* [386Enh]
*
* WOAFont=<fon filename>
*
* Status: Public
* Default: dosapp.fon
* Purpose:
*
* This setting allows the user to specify which Terminal font
* file should be loaded when DOS box is started.
*
* To change:
*
* Use Notepad to edit the SYSTEM.INI file.
*
*
* [NonWindowsApp]
*
* DisablePositionSave=<Boolean>
*
* Status: Public
* Default: 0 (FALSE)
* Purpose:
*
* When FALSE, the position and font used in a non-Windows
* application is saved in the application's PIF file when
* you exit the application. When TRUE, the position, fonts, and
* toolbar state of a non-Windows application whose settings
* have not been previously saved in the DOSAPP.INI file will
* not be saved.
*
* If enabled, the setting can be overridden for each
* non-Windows application by selecting the Save Settings On
* Exit check box in the Font dialog box.
*
* To change:
*
* Use Notepad to edit the SYSTEM.INI file.
*
* Compatibility notes:
*
* In Windows 3.x, the "position save" (and font) information was
* saved in DOSAPP.INI, and although we will still read DOSAPP.INI
* in the absence of any information in the PIF file, we only *write*
* settings back to the PIF file. DOSAPP.INI should be considered
* obsolete.
*
*
* TTFont=<fontname>
*
* Status: ?
* Default: Courier New // FEATURE -- this should be a TT OEM font
* Purpose:
*
* This setting allows the user to specify which TrueType font
* will be used in a DOS box. It must be an OEM font.
*
* To change:
*
* Use Notepad to edit the SYSTEM.INI file.
*
*
* TTInitialSizes=<i1 i2 i3 i4 ... i16>
*
* Status: ?
* Default: 4 5 6 7 8 9 10 11 12 14 16 18 20 22 36 72
* Purpose:
*
* This setting allows the user to specify which font sizes
* WinOldAp initially builds for the TrueType fonts in a DOS
* application window.
*
* At most 16 font sizes can be requested.
*
* Note that this INI entry is consulted only the first time
* Windows is restarted after changing video drivers or fonts.
*
* To change:
*
* Use Notepad to edit the SYSTEM.INI file.
*
*
* TTHeuristics=<i1 i2 i3 i4 i5 i6 i7 i8 i9>
*
* Status: Public
* Default: 5000 1000 0 1000 5000 1000 0 1000 1
* Purpose:
*
* These integers control the way Windows chooses the font to
* display for DOS applications running inside a window if you
* have chosen "Auto" as the font size.
*
* The parameters are named as follows:
*
* i1=XOvershootInitial
* i2=XOvershootScale
* i3=XShortfallInitial
* i4=XShortfallScale
* i5=YOvershootInitial
* i6=YOvershootScale
* i7=YShortfallInitial
* i8=YShortfallScale
* i9=TrueTypePenalty
*
* Each penalty value may not exceed 5000.
*
* When Windows needs to select a font for use in a DOS
* application's window, it goes through the list of font
* sizes available and computes the "penalty" associated
* with using that font. Windows then selects the font with
* the smallest penalty.
*
* The horizontal penalty is computed as follows:
*
* Let dxActual = <actual window width>
* Let dxDesired = <font width> * <characters per line>
*
* If dxActual = dxDesired:
* xPenalty = 0
* If dxActual < dxDesired:
* Let Ratio = 1 - dxDesired / dxActual
* xPenalty = XOvershootInitial + Ratio * XOvershootScale
* If dxActual > dxDesired:
* Let Ratio = 1 - dxActual / dxDesired
* xPenalty = XShortfallInitial + Ratio * XShortfallScale
*
* The vertical penalty is computed similarly.
*
* Note that the Ratio is always a fraction between 0 and 1.
*
* The penalty associated with a font is the sum of the vertical
* and horizontal penalties, plus the TrueTypePenalty if the font
* is a TrueType font.
*
* The default value of 1 for the TrueTypePenalty means that,
* all other things being equal, Windows will select a raster
* font in preference to a TrueType font. You can set this
* value to -1 if you wish the opposite preference.
*
* To change:
*
* Use Notepad to edit the SYSTEM.INI file.
*
* Internals:
*
* Even though floating point appears in the computations,
* everything is really done in integer arithmetic.
*
* Pixels are NEVER MENTIONED anywhere in the penalty computations.
* (All pixel values are divided by other pixel values, so that
* we get a dimensionless number as a result.)
* This keeps us independent of the display resolution as well
* as the display aspect ratio.
*
* Since the stretch and shrink are taken as fractions of the
* larger dimension, this keeps us from penalizing large
* differences by too much. This is important because there
* isn't much visible difference between being ten times too
* big and being eleven times too big, but there is a big
* difference between being just right and being twice as big.
*
* We must be careful not to let the maximum possible penalty
* exceed 32767. This is done by making sure that each
* dimension cannot produce a penalty of greater than 10000
* (5000+5000), and that the TrueTypePenalty is at most 5000.
* This makes the maximum possible penalty 25000.
* This range checking is done by FontSelInit.
*
*
* TTNonAspectMin=<x y>
*
* Status: Public
* Default: 3 3
* Purpose:
*
* These integers control the minimum width and height font that
* Windows will attempt to create automatically in response to a
* resize operation when TrueType fonts in DOS boxes are enabled
* and the "Auto" font size is selected.
*
* These values prevent Windows from creating visually useless
* fonts like 10 x 1 or 1 x 10. The default values prevent Windows
* from trying to create X x Y fonts if X < 3 or Y < 3.
*
* TTNonAspectMin is not consulted if the font is being created at
* its default aspect ratio. In other words, Windows will create,
* for example, a 1 x 3 font, if 1 x 3 is the standard aspect ratio
* for a 3-pixel-high font.
*
* To permit all aspect ratios, set the values to "0 0".
*
* To forbid all aspect ratios except for the standard aspect ratio,
* set the values to "-1 -1".
*
* [TTFontDimenCache]
*
* dxWidthRequested dyHeightRequested=dxWidthActual dyWidthActual
*
* Status: Private
* Default: Null
* Purpose:
*
* The [FontDimenCache] section contains information about
* TrueType font sizes that have been created. Each entry
* has as the keyname the width and height that were passed
* to CreateFont and has as the value the width and height of
* the font that was actually created.
*
* Internals:
*
* Inspected by AddTrueTypeFontsToFontList.
* Set by AddOneNewTrueTypeFontToFontList.
*

*
* [Dos Applications]
*

* wWinWidth wWinHeight length flags showCmd ptMinPositionX
* ptMinPositionY ptMaxPositionX ptMaxPositionY
* rcNormalLeft rcNormalTop rcNormalRight rcNormalBottom>
*
* Status: Private
* Purpose:
*
* These values are used to restore a DOS application's window
* to the state it was in when the DOS app last exited normally.
*
* The values are taken directly from the INIINFO structure, qv.
*
* The values of ptMinPositionX and ptMinPositionY are always -1,
* since we do not try to preserve the icon position.
*
* If wFontHeight has the high bit set, then the font that
* should be used is a TrueType font.
*
* If wFontWidth = 1 and wFontHeight = -1, then
* Auto-font-selection is active.
*
* Compatibility notes:
*
* In Windows 3.x, the "position save" (and font) information was
* saved in DOSAPP.INI, and although we will still read DOSAPP.INI
* in the absence of any information in the PIF file, we only *write*

*
* TTFontTolerance=<i>
*
* Status: Public

* Purpose:
*
* This setting indicates how large a penalty (see TTHeuristics)
* Windows should tolerate before trying to synthesize new font
* sizes from TrueType fonts.
*
* Decreasing this value will result in a tighter fit of the

*
* REMARKS
* This should not be thought of as a function that opens a file somewhere
* on the disk (although that's usually the effect), but rather as an
* property structure allocator that is optionally initialized by disk data
* (currently, the file does not even remain open after this call). So the
* main reason for failure in this function will be either a low memory
* condition *or* inability to open a specific PIF file.
*
* The rules for PIF file searching are as follows:
*
* If not a .PIF file:
* Search in current directory.
* Endif.
*
* If path components were specified:
* Search in specified directory.
* Endif.
*
* Search in PIF directory.
* Search the path.
*
* Note that this differs from the Windows 3.1 PIF search algorithm, which
* was...
*
* Search current directory.
* Search the path.
* Search in application directory.
*
* This was a really bogus search order. Fortunately, it seems that
* very few people relied on it.
*
* Things to watch out for when dorking the PIF file search order:
*
* Make sure editing PIF properties from the shell works. (I.e.,
* if a full path to a PIF is given, then use it; don't search.)
*
* Extra special thing to watch out for when dorking the PIF file
* search order:
*
* MS Delta execs its child process as follows:
*
* CreatePif("C:\DELTA\DELTABAT.PIF");
* SetCurrentDirectory("C:\RANDOM\PLACE");
* WinExec("C:\TMP\DELTABAT.BAT", SW_HIDE);
*
* It expects the PIF search to pick up C:\DELTA\DELTABAT.PIF
* from the path, even though the WinExec supplied a full path.
