in the newDoc parameter.
Input:
iFileSpec: If not NULL the file is read to obtain the document contents after the object is
successfully allocated. If NULL you start with an empty document.
iWindow: Required. The window in which the document is going to be displayed.
iFrame: If text-area does not fill the entire window. This specifies the area to fill. Can be NULL.
In which case, the window's portRect is used as the frame.
iFrameOptions: Specify the options to be supported by this frame. The available options are support
for cutting and pasting movies and sound, handle scrollbars and handle grow box in the
frame.
iFrameType: Specify the type of frame to be used. In MLTE version 1.1 and earlier, only
kTXNTextEditStyleFrameType is supported.
iFileType: Specify the primary file type. If you use kTextensionTextFile files will be saved
in a private format (see xxx). If you want saved files to be plain text files you should
specify 'TEXT' here. If you specify 'TEXT' here you can use the frameOptions parameter to
specify whether the TEXT files should be saved with 'MPSR' resources or 'styl' resources.
These are resources which contain style information for a file, and they both have there
own limitations. If you use 'styl' resources to save style info your documents can have as
many styles as you like however tabs will not be saved. If you use 'MPSR' resources only the
first style in the document will be saved (you as client are expected to apply all style
changes to the entire document). If you truly want rich documents which can potentially
contain graphics and sound you should specify kTextensionTextFileOutput. If you want a plain
text editor like SimpleText specify that style information by saved via 'styl' resources.
If you want files similar to those output by CW IDE, BBEdit, and MPW specify that style
information be saved in a 'MPSR' resource.
Output:
OSStatus: function result. If anything goes wrong the error is returned. Success must be complete.
That is if everything works, but there is a failure reading a specified file the object
is freed.
oTXNObject: Pointer to the opaque datastructure allocated by the function. Most of the subsequent
functions require that such a pointer be passed in.
oTXNFrameID: Unique ID for the frame. <Note in version 1.0 this value is always set to 0>

TXNNewObject which can later be asked to return it.

Find a piece of text or a graphics object.
Input:
iTXNObject: opaque TXNObject obtained from TXNNewObject.
iMatchTextDataPtr ptr to a MatchTextRecord which contains the text to match, the length of that text
and the TextEncoding the text is encoded in. This must be there if you are looking
for Text, but can be NULL if you are looking for a graphics object.
iDataType The type of data to find. This can be any of the types defined in TXNDataType enum
(TEXT, PICT, moov, snd ). However, if PICT, moov, or snd is passed then the default
behavior is to match on any non-Text object. If you really want to find a specific
type you can provide a custom find callback or ignore matches which aren't the precise
type you are interested in.
iStartSearchOffset The offset at which a search should begin. The constant kTXNStartOffset specifies the start
of the objects data.
iEndSearchOffset The offset at which the search should end. The constant kTXNEndOffset specifies the end
of the objects data.
iFindProc A custom callback. If will be called to match things rather than the default matching
behavior.
iRefCon This can be use for whatever the caller likes. It is passed to the FindProc (if a FindProc
is provided.
Output:
oStartMatchOffset absolute offset to start of match. set to 0xFFFFFFFF if not match.
oEndMatchOffset absolute offset to end of match. Set to 0xFFFFFFFF is no match.
The default matching behavior is pretty simple for Text a basic binary compare is done. If the matchOptions say
to ignore case the characters to be searched are duplicated and case neutralized. This naturally can fail due
to lack of memory if there is a large amount of text. It also slows things down. If MatchOptions say
find an entire word that once a match is found an effort is made to determine if the match is a word. The default
behavior is to test the character before and after the to see if it is White space. If the kTXNUseEncodingWordRulesBit
is set than the Script Manager's FindWord function is called to make this determination.
If the caller is looking for a non-text type than each non-text type in the document is returned.
If more elaborate ( a regular expression processor or whatever ) is what you want then that is what the FindProc is
for.

/*
* TXNRegisterScrollInfoProc()
*
* Discussion:
* If your application is drawing and handling its own scrolling
* widgets use this function to register a TXNScrollInfoUPP. If you
* register a TXNScrollInfoUPP it will be called every time MLTE
* would normally update the values and maximum values of an MLTE
* scrollbar. For example when the user types the return key to add
* a new line at the end of their text MLTE will calculate a new
* maximum value. If you have registered a TXNScrollInfoUPP it will
* be called with this nex maximum value. To turn off the callbacks
* call TXNRegisterScrollInfoProc with a value of NULL for the
* iTXNScrollInfoUPP.
*
* Parameters:
*
* iTXNObject:
* Opaque TXNObject obtained from TXNNewObject.
*
* iTXNScrollInfoUPP:
* A universal procedure pointer.
*
* iRefCon:
* A refcon that is passed to the callback.
*
* Availability:
* Non-Carbon CFM: in Textension not yet available
* CarbonLib: not available in CarbonLib 1.x, is available on Mac OS X version 10.2 and later
* Mac OS X: in version 10.2 and later
