Family API

Shared API for DOS and OS/2 to produce binary dual mode applications which can be run without recompilation

Build status

At the present time we have:

  • VIOCALLS at level of OS/2 1.0 (both real and protected mode DOS/OS2, except Register/Deregister)
  • MOUCALLS at level of OS/2 1.0 (both real and protected mode DOS/OS2, except Register/Deregister)
  • KBDCALLS at level of OS/2 1.0 (both real and protected mode DOS/OS2, except Register/Deregister)
  • BVSCALLS at level of OS/2 1.0 (both real and protected mode DOS)
  • BMSCALLS at level of OS/2 1.0 (both real and protected mode DOS)
  • BKSCALLS at level of OS/2 1.0 (both real and protected mode DOS)
  • DOSCALLS in progress

Implementation design

osFree Family API consist of 2 levels:

KAL - is a Kernel Abstraction Layer which implements kernel specific functions. OS/2 API layer - kernel independed part which is same as in DOS, OS/2 or other kernel.

At the current design only core DOSCALLS functions uses KAL functions.

Kernel Abstration Layer functions list

(This is draft, still most functions not in KAL, but in corresponding DLLs)

KalDevIOCtl - is a most complex function. It is implements DosDevIOCtl background. Most of I/O Subsystem functions (Kbd, Vio, Mou, Bms, Bvs, Bks) uses DosDevIOCtl to provide implement corresponding functions. This way I/O Subsystems shares same code in DOS and OS/2.

KalGetInfoSeg - provides access to Global Info Segment and Local Info Segment. DOSCALLS functions uses GIS or LIS obtained via DosGetInfoSeg, if it possible, to provide information.

KalQProcStatus - another generic interface which allow to access internal structures. http://svn.netlabs.org/repos/fm2/tags/FM2-3_15_00/dll/procstat.h http://www.edm2.com/index.php/DQPS.H http://archive.retro.co.za/CDROMs/DrDobbs/CD%20Release%2012/articles/1994/9408/9408n/9408n.htm#00b2_0048
