   I recently found out about this:   
      
   https://learn.microsoft.com/en-us/windows/win32/debug/pe-format#   
   indows-subsystem   
      
   IMAGE_SUBSYSTEM_POSIX_CUI   
   7   
   The Posix character subsystem   
      
      
   And I see there is also:   
      
   IMAGE_SUBSYSTEM_OS2_CUI   
   5   
   The OS/2 character subsystem   
      
      
   So yes - I already know that the POSIX support   
   is crap and meant for marketing purposes - but   
   it's probably good enough for me anyway.   
      
   I do most of my development under Windows 2000.   
      
   And I don't need Microsoft's libraries - I can   
   provide my own with PDPCLIB (most of it likely   
   already exists).   
      
   What I need to know is - how did a call to   
   open() or whatever get resolved? Did it do the   
   same as Linux, ie INT 80H?   
      
   Whatever the interrupt or DLL reference - is   
   this documented anywhere?   
      
   And with regard to the OS/2 one - I know that   
   Windows 2000 can run OS/2 1.x console mode   
   applications - but those are NE, not PE. This   
   documentation is for PE. Does an OS/2 2.x   
   subsystem exist in Windows 2000?   
      
   Thanks. Paul.
