-Ken's ATR manipulation C library. This has only been used under Microsoft
-C/C++ version 8.0. It will probably work on 7.0 and possibly earlier
-versions. You are on your own for porting to other compilers.
-
-With Microsoft C, you must use the /Zp option to pack structure members
-on byte boundries. I have no idea how this translates to other compilers.
-
-
-To Do
-1 Clean up warnings + make more portable
-2 Allow opening write-protected ATRs
-3 Allow more than one reference to an ATR file to be opened so more
- than one atari file can be opened at once.
-4 More specific error returns
-5 Implement XFD handling
-6 Create documentation
-7 Optimize if necessary
-8 Implement DCM images (maybe)
-
-----------------------------------------------------------------------------
-
-This source is a work in progress and in distributed for those wanting
-to write ATR related programs. I had planned to tidy them up a lot before
-releasing them, but have been sidetracked by other projects. Feel free to
-use them in your own freeware and public domain programs if credit is given.
-
-These have all been compiled with Microsoft C version 8.0. They should
-compile with 7.0 and possibly earlier versions. They may need
-some tweaking for use on other compilers. The /Zp option must be used
-on the Microsoft compiler to pack structures on byte boundries. I don't
-know how this is done on other compilers.
-
-Files:
-The file that does all of the work is ATR.C. The other programs do some
-basic processing and call fucntions in ATR.C to do the work.
-
-The other C files, all build the ATR utilities that are on my Atari
-web page. They, of course must be linked with the main ATR file.
-
-There are two header files: ATR.H and ATRDOS.H both of which will be
-required by most programs. ATR.H contains definitions for ATR image related
-functions. ATRDOS.H contains definitions for referencing Mydos and
-Atari Dos files located on ATR images. Hopefully the short descriptions
-in the source are enough to allow one to figure out what each function does.
-There is also a third header file with the Boot disk routine.
-
-
-Note: You cannot open write protected images yet and you can only have
-one ATR open at a time. If you Open an ATR and then call a function like
-ATRDirectory, an error will result. You must Close the ATR first, call
-the function and then reopen the ATR. This also means you can't have two
-files open in a single ATR at the same time. This will hopefully be
-rectified soon. Good Luck.

+
+ Parameters:
+ fileInfo - A pointer to your file info structure in which to return
+ the information. This structure should still have
+ unmodified info from the last AtariFindFirst or
+ AtariFindNext function call.
+
+ Returns:
+ 0 if a match was found.
+ -1 if a match was not found.
+ a positive number if an error occurred.
+
+CreateBootAtr - int CreateBootAtr( char *atrName, char *fileName)
+
+ Description:
+ Will create a minimally sized bootable ATR image from an Atari
+ Executable. The ATR file will be just long enough to hold
+ three boot sectors and the file's data. The executable must
+ consist of only one file and not need DOS for any reason. Note:
+ Not all Atari computer and peripheral emulators may support
+ non-standard sized images. When booting from the image, the
+ screen will turn red if an error occurs.
+
+ Parameters:
+ atrName - The ATR file name.
+ fileName - The name of the MSDOS file to convert.
+
+ Returns:
+ 0 for success.
+
+
+ExtractExeFromBootAtr - long ExtractExeFromBootAtr( char *atrName,
+ char *fileName)
+
+ Description:
+ Undoes a CreateBootAtr by extracting the original executable from
+ the ATR image.
+
+ Parameters:
+ atrName - ATR file name of a disk created with CreateBootAtr.
+ fileName - The name of the MSDOS file to write the output to.
+
+ Returns:
+ Returns 0 for error, or file length in bytes of file extracted.
+ An error will result if the file was not created with CreateBootAtr.
+

+Dos Functions - These functions are used to reference atari files

+***********************************************************************
+
+OpenAtariFile - AtariFilePtr OpenAtariFile( char *atrName, char *fileName,
+ byte mode)
+
+ Description:
+ Opens file in an ATR image in the mode specified: ATARI_OPEN_READ,
+ ATARI_OPEN_WRITE, or ATARI_OPEN_DIR. ATARI_OPEN_DIR is not supported
+ yet.
+
+ Parameters:
+ atrName - Name of ATR image in which to look for the file.
+ fileName - Filename of the atari file in the ATR image to open.
+ mode - ATARI_OPEN_READ to open the file for read, ATARI_OPEN_WRITE
+ to open it for write. "Or" the two together for both.
+ ATARI_OPEN_DIR is not implemented yet.
+
+ Returns:
+ An Atari file pointer that can be used in functions to read or
+ write from the file. NULL is returned on error.
+
+
+ReadAtariFile - long ReadAtariFile( AtariFilePtr atFile, char *buffer,
+ long bytes )
+
+ Description:
+ Reads bytes bytes from an open atari file (opened with OpenAtariFile).
+
+ Parameters:
+ atFile - An Atari file pointer that was set from an OpenAtariFile function
+ call
+ buffer - A pointer to a buffer to read the bytes into. Must be big
+ enough to hold the number of bytes requested.
+ bytes - Number of bytes to read.
+
+ Returns:
+ Number of bytes actually read. May be less than bytes if EOF was
+ reached. You can use EofAtariFile to see if the EOF was reached
+ or if an error occurred.
+
+
+CloseAtariFile - int CloseAtariFile( AtariFilePtr atFile )
+
+ Description:
+ Closes an atari file opened with OpenAtariFile.
+
+ Parameters:
+ atFile - An atari file pointer used in an OpenAtariFile function
+ call.
+
+ Returns:
+ 0 if successful.
+
+
+EofAtariuFile - int EofAtariFile( AtariFilePtr atFile )
+
+ Description:
+ Determines if pointer is at the end of an atari file.
+
+ Parameters:
+ atFile - An atari file pointer returned from an OpenAtariFile
+ function call.
+
+ Returns:
+ Returns 1 if at EOF of atari file, 0 if not
+
+
+AtariDirectory - int AtariDirectory( char *atrName, char *pattern)
+
+ Description:
+ Displays atari directory of disk image to screen. The disk image
+ must be Atari Dos, MyDos, or compatable.
+
+ Parameters:
+ atrName - The ATR file name.
+ pattern - filename mask to use. use "*.*" for all files.
+
+ Returns:
+ 0 for no errors.
+
+
+AtariFileSize long AtariFileSize( char *atrFile, char *fileName )
+
+ Description:
+ Get the actual length in bytes of an atari file in an ATR image.
+
+ Parameters:
+ atrName - The ATR file name.
+ fileName - The atari filename in 8.3 to look for. No wildcards.
+
+ Returns:
+ Length of file in bytes or -1 for error.
+
+
+ExtractAtariFile - int ExtractAtariFile( char *atrFile, char *fileName,
+ char *dosPath )
+
+ Description:
+ Extracts an Atari file from an ATR image. Atari Dos and MyDos
+ formats are supported for the image.
+
+ Parameters:
+ atrName - The ATR file name.
+ fileName - Atari filename in 8.3 format. Wildcards * and ? are
+ allowed. If verbose is on, files will be displayed
+ as they are extracted.
+ dosPath - Directory to store the file in. File is stored with same
+ name in dosPath directory. (don't add the trailing '\').
+ Use NULL for dosPath to extract to current directory.
+
+ Returns:
+ number of file extracted. If the result is negative, an error
+ occured but the Absolute value of that number of files were
+ extracted successfully before the error occurred.
+
+
+FixAtariFileNo - int FixAtariFileNo( char *atrName, char *fileName,
+ int fileNo )
+
+ Description - For atari dos, will fix the file no in each sector within
+ the file. Used internally after a directory is sorted but
+ their may be other uses. For larger MyDos disks the
+ function has no effect. I currently don't know how to
+ distinquish DOS 2.5 1050 double density disks and Mydos
+ disks so this may not work on Dos 2.5 1050 double density
+ disks.
+
+ Parameters:
+ atrName - The ATR file name.
+ fileName - Atari filename in 8.3 format to fix. No wildcard's
+ allowed.
+ fileNo - File number to give the file. This could probably be
+ made to be automatic.
+
+ Returns:
+ 0 for success.
+
+
+SortAtariDir - int SortAtariDir( char *atrName )
+
+ Description:
+ Sorts the files in an ATR image. BUT: 1. May not work on Dos 2.5
+ 1050 double density disks. 2. Doesn't allow DOS.SYS and DUP.SYS,
+ or other files to be specified not to be sorted.
+
+ Parameters:
+ atrName - The ATR file name.
+
+ Returns:
+ 0 for success.
+
+

+
+
+SetVerbose int SetVerbose( int verb )
+
+ Description:
+ Used to set verbose flag to 1 (on) or 0 (off). Currently the only
+ function that uses this is ExtractAtariFile.
+
+ Parameters:
+ verb - 1 for verbose, 0 for not verbose
+
+ Returns:
+ Previous state of verbose flag.
