Libi86 Versions Save

This is a FreeDOS (.zip) package for my libi86 library of routines for MS-DOS programs, meant to be used with the IA-16 GCC toolchain.

Changes since 15 Sep 2021:

• Several new functions:
  • _bios_printer (…) and _bios_serialcom (…), in <bios.h>;
  • Borland _searchpath (·), in <dir.h>;
  • _getdcwd (…), and optionally getcwd (, ) and _getcwd (, ), in <direct.h>;
  • _dos_getftime (…), _dos_gettime (·), _dos_setblock (…), _dos_setdate (·), _dos_setftime (…), _dos_settime (·), and Borland keep (, ), in <dos.h>;
  • _DPMIGetCapabilities (…), _DPMIGetVendorSpecificAPI (·), _DPMIGetVirtualInterruptState (), and _DPMIIdle (), in <dpmi.h>;
  • _displaycursor (·) and _setcolor (·), in <graph.h>;
  • _fullpath (…), in <libi86/stdlib.h>; and
  • _fmemcmp (…), in <libi86/string.h>.
• _setbkcolor (color) (<graph.h>) is also partially implemented for IA-16 GCC. Currently the color must be a compile-time constant, and must be an indexed colour, not an RGB triplet.
• Bug fixes:
  • _makepath (…) and _splitpath (…) now work properly on systems such as MS-DOS 5.0/V (Japanese) where file names might contain double-byte character sequences.
  • Various other minor fixes.

libi86 now also officially supports the Amsterdam Compiler Kit with the msdos86 target platform. However, this currently needs to be built from the source code.

Changes since 18 Apr 2021:

• Several new functions have been implemented:
  • Watcom-compatible functions _dos_creat (…), _dos_creatnew (…), _dos_getdate (·), _dos_getdiskfree (…), _dos_keep (…), _dos_open (…), _dos_read (…), and _dos_write (…), in <dos.h>;
  • Borland-compatible functions peek (…), peekb (…), poke (…), and pokeb (…), also in <dos.h>;
  • and more.
• Other minor internal changes.

I am also in the process of porting libi86 to the Amsterdam Compiler Kit's x86 targets — in addition to IA-16 GCC — however this is still not quite complete yet.

This is a FreeDOS (.zip) package for my libi86 library of routines for MS-DOS programs, meant to be used with the IA-16 GCC toolchain.

Changes since 27 Feb 2021:

• The library is now released under the permissive 3-clause BSD License. (Previously it was only released under the GNU GPL v2 or above.)
• Some minor bugs have been fixed:
  • <conio.h> now correctly sets the console device (CON) to raw mode if stdin does not already point to the console.
  • <dos.h> now declares the Borland-specific bdosptr (...) function only if _BORLANDC_SOURCE is enabled.

Changes since 1 Dec 2020:

• The library now implements
  • Watcom-compatible functions _splitpath, _makepath, _ltoa, _ultoa, _lltoa, _ulltoa, _dos_setdrive, _dos_findfirst, _dos_findnext, _dos_findclose, _dos_commit, _dos_getvect, _dos_setvect; and
  • functions _DPMIAllocateDOSMemoryBlock (·) and _DPMIFreeDOSMemoryBlock (·) compatible with Watcom internal interfaces.
• If Borland compatibility mode is enabled (_BORLANDC_SOURCE), the library now also implements
  • a Borland-compatible gettextinfo (·) function; and
  • special Borland-compatible versions of the functions int86, int86x, intdos, intdosx, etc.
• Various other minor bug fixes and improvements have been made.

Changes since 10 Jul 2020:

• libi86 is now released under the GNU Lesser General Public License (LGPL) version 2 or above.
  • Previously it was released under the GNU LGPL v3 or above.
• The library now includes implementations of "advanced" <conio.h> functions as in Borland Turbo C++. These can be used to set video modes, display coloured text, move the cursor, and so on.
  • To use these in a program, define the macro _BORLANDC_SOURCE before including <conio.h>.
  • A few functions are still not implemented: gettext (...), gettextinfo (·), movetext (...), and puttext (...).
• Also added are
  • an initial partial implementation of <graph.h> routines as in Open Watcom and
  • an implementation of DPMI functions — via <dpmi.h> — as in Open Watcom's internal interfaces
  • an _fstrlen (·) function.
• The functions _dos_allocmem (...) and _dos_freemem (·) now also work in DPMI mode.
• Various other minor bug fixes and improvements have been made.
