//
// TO COMPILE:
// ===========
//
// Should compile in Linux, macOS, and Windows (Cygwin) just by typing:
//
// gcc EpsLin_v1.56.c -o epslin
//
// In Windows you have to install "fdrawcmd.sys" from
// http://simonowen.com/fdrawcmd/
//
// and get the header file from
// http://simonowen.com/fdrawcmd/fdrawcmd.h
//
// and put it in the same directory as the EpsLin source.
//
// HISTORY
// =======
//
// v9.99: [FUTURE]
// - Optional "allowed" devices list to minimize
// unintentional writes to devices like system
// hard disk etc.. for Format and ImageCopy
// THIS COULD SAVE YOUR DAY (or even two)..!
// - Check mode and only EFE erase/put use the
// 'I' write to check if 's' media type..
// - Use 's' media type in Get and in GetFat/SetFat
//
// vX.XX: [FUTURE]
// - TODO: allow a sector offset to be supplied; needed to
// handle direct access of SCSI2SD-ready SD cards
// - TODO: check for Ensoniq volume signatures prior to any
// non-Format related routines
// - TODO: add recursive mode for GetEFE
// - TODO: create named sub-directories when GetEFE is used
// such as 'root', etc. to hold EFEs on export
//
// v1.56:
// - Rudimentary support for TS10/TS12 file types.
//
// v1.55:
// - Support for 4GB partitions (i.e. prints the free blocks/bytes correctly)
//
// v1.54:
// - Multiple compiler warnings have been corrected.
// - [macOS] Fixed "Abort trap: 6" bug on multi-part reporting.
//
// v1.53:
// - Fixed issue with "Part_xx" being appended to full path
// rather than base filename.
// - ASR SuperDisk is now allowed as a split target.
//
// v1.52:
// - Made newline characters compatible with Windows apps,
// such as Notepad, et al.
//
// v1.51:
// - Fixed error with additional IsEFE checks from v1.47.
// - Entries which can't be exported are now skipped by GetEFE.
//
// v1.50:
// - Added preliminary macOS support, although issues may exist.
//
// v1.47:
// - Added handling for EFEs with "/" in Ensoniq filename.
// - Fixed crash in PutEFE when directory full (39th entry).
// - Improved wildcard/globbing usage, although still not
// 100% case-insensitive under Windows, as is ideal.
// - Null sector no longer used for vanity message, etc.
// - Improved EFE/EFA/INS checking before PutEFE is allowed.
// - Added INS extension support as an alias for EFE.
// - Added Directory and Disk Information mode (read-only).
// - Show usage help when '?' or unknown arguments used.
// - Show usage help when run without arguments rather than
// than showing potential "fdrawcmd.sys" error.
//
// v1.46:
// - [Windows] Cygwin component in non-contiguous portion
// of the GetEFEs routine caused *some* EFEs not to extract
// properly; routine was given an overhaul.
// - Corrected SuperDisk support in PutEFE/GetMedia/EraseEFEs.
// - Removed path from filename when printing report.
//
// v1.45: (forked by Thomas Arashikage)
// - [Windows] Tweaks to help compile under Cygwin.
// - [Windows] Fixed FAT block calculation in GetEFE and GetInfo,
// as values could sometimes be off by one!
// - [Windows] ReadBlock function altered to avoid abort on error.
// - [Windows] Too restrictive permissions on newly created
// files (IMG, EFE, EDE, et al) were lessened.
// - Corrected disk label size and default string.
// - Added ASR-Macro to identified file types.
// - Added SuperDisk (255 block) support for EPS16 and ASR which
// is only applicable with HFEs under floppy emulators.
//
// v1.42:
// - [Windows] Had to optimize the I/O functions involved
// when EFEs are GET/ERASED/PUT from/to media. This increased
// the run time memory consumption, as the whole FAT
// table are loaded to memory in order to avoid
// seeks in CD-ROM (/dev/scd) and to write Iomega
// Zip drives which don't support single byte writes.
// As the load/save time of the FAT table depends on the size
// of the media, it _might_ take quite a long time for some media,
// thus making the get/put/erase slow. As the Zip drive is the only
// device to test this, it happens to take only 2 seconds to
// read+write the table, so it's quite reasonable.
// If you send me a SCSI device, that is very slow for this reason,
// I'll try to optimize the functions more - until that,
// for me it's fast enough.. ;-)
// - Options that accept parameter 'a' (= all), now starts
// at idx 1 (not 0 as previous versions).
// - Added progress info when EFEs are put/get.
//
// v1.41:
// - [Windows] Added support for /dev/scd layer in Cygwin..
// Since the seeks are possible only in 2048 byte multiples
// had to make some mods to ReadBlock etc. functions.
// Minor penalties in performance..
//
// v1.40: NOW PORTED TO WINDOWS!!
// - Uses Simon Owens "fdrawcmd.sys" (http://simonowen.com/fdrawcmd/)
// driver for low-level floppy access. Thanks Simon!
// - Minor differences between Cygwin (Win32) and Linux in command
// line arguments (for ex. Cygwin requires allways parameter for -p)
// - Should support also SCSI devices through Cygwin layer
// - Some minor fixes
//
// v1.37:
// - Fixed nasty bug in dir-argument (-d) parsing, that
// sometimes leads an error "ERROR: Index '0' is not a directory!".
// Hopefully now solved..
// - More investigation had to be done to find out how EPS knows, when to
// load Song (instruments has the mask,that tells what location to load -
// for song there are no such info). It seems that if index is 0, it is
// not counted as a valid song, so no song data is loaded.
// The BankInfo function is modified based on that knowledge.
//
// BTW: You can make deeper dir structures with EPS than banks can handle, so..
// don't do it if you want to use files in those dirs with banks.. :-)
//
// - Minor changes to BankInfo output. Paths starts with '/' and ends with no '/'
//
//
// v1.36:
// - Option to join multifile EFEs to single EFE file
//
// v1.35:
// - Added missing CR,LF,EOF bytes to EFE header (cosmetic)
// - Option to show info from Ensoniq Bank EFE
// - Option to split EFE to multifile parts added
// - Option to print directory listing in compact mode to make the
// parsing for external programs easier.
// - Some code clean-ups...
//
// v1.34:
// - Support for Multi Files (ie. instruments, that don't fit in one floppy)
// - Fixed (new) gcc errors
//
// NOTES!
// ======
//
// * Some _commercial_ EPS/ASR tools corrupts the FAT.. You should avoid
// those programs.. IF you have to use them, please at least check
// the disks and image-files before use with EpsLin 'check' option (-C).
// If you use those corrupted disk/images you may lose data!!
//
// TODO:
// =====
//
// [CYGWIN]:
// !! PutEFE doesn't work without idx number.. It's the Optget that
// doesn't support optional arguments, so we'll wait for proper version...
//
// [GENERAL]
//
// !! Format -fi optimize (now redundancy in allocated fat_block write)
//
// !! MkDir max level.. (Bank can load files only max 11-level deep dirs)
//
// !! Fix MKDIR Kludge in PutEFE...
//
// !! Using Floppy with ReadImage sometimes mess up the FD controller !?
//
// !! Add 'image copy' -feature (ie. make it possible to transfer
// data in SCSI HD <-> ZIP, Zip requires '0x6d' at first byte in disk)
//
// ! WAV to EFE & EFE to WAV conversions.
//
// ! In EPS, the OS has to be in one contiguous part
// * ASR doesn't mind...
//
// - Dir-transfer function (copy files recursively..)
// Useful to transfer whole dir structures from medium to an another.
// (Must take care of changing SCSI-ID in Bank-files ?)
//
// - Erase: Recurse Dirs !!
//
// - Format_n_Write -support (?!)
