|
** Filename: Host.h
|
|
** Purpose: This is the system independent typedefs and defines
|
|
** Author: MN, JG, MD
|
|
** Version: 5.4.1
|
|
** History: 11/7/94 MCD received the modification that Lennart made
|
|
** to port to 32 bit world and modify this file so that it
|
|
** will be shared between platform.
|
|
** 11/9/94 MCD Make MSW32 subset of MSW. Now MSW means
|
|
** MicroSoft Window and MSW32 means the 32 bit worlds
|
|
** of MicroSoft Window. Therefore you want the environment
|
|
** to be MicroSoft Window and in the 32 bit world -
|
|
** _WIN32 must be defined by your compiler.
|
|
** 11/30/94 MCD Incorporated comments received for more
|
|
** readability and the missing typedef for FLOAT.
|
|
** 12/1/94 MCD Added PFVOID typedef
|
|
** 5/1/95 MCD. Made many changes based on the inputs.
|
|
** Changes:
|
|
** 1) Rearrange the #ifdef so that there're definitions for
|
|
** particular platforms.
|
|
** 2) Took out the #define for computer and environment
|
|
** that developer can uncomment
|
|
** 3) Added __OLDCODE__ where the defines will be
|
|
** obsoleted in the next version and advise not to use.
|
|
** 4) Added the definitions for the following:
|
|
** FILE_HANDLE, MEMORY_HANDLE, BOOL8,
|
|
** MAX_INT8, MAX_INT16, MAX_INT32, MAX_UINT8
|
|
** MAX_UINT16, MAX_UINT32, MAX_FLOAT32
|
|
** 06/19/96 MCD. Took out MAX_FLOAT32
|
|
** 07/15/96 MCD. Fixed the comments error
|
|
** Add back BOOL8.
