Name
  osifctyp.h - TADS OS interface datatype definitions
Function
  Defines certain datatypes used in the TADS operating system interface
Notes
  DO NOT MODIFY THIS FILE WITH PLATFORM-SPECIFIC DEFINITIONS.  This file
  defines types that are part of the portable interface; these types do
  not vary by platform.

  These types are defined separately from osifc.h so that they can be
  #include'd before the OS-specific header.  osifc.h is included after
  the OS-specific header.

 *   File types.  These type codes are used when opening or creating a

 *   The type os_filetype_t is defined for documentary purposes; it's
 *   always just an int.
