2 ** Filename: Host.h
3 ** Purpose: This is the system independent typedefs and defines
4 ** Author: MN, JG, MD
5 ** Version: 5.4.1
6 ** History: 11/7/94 MCD received the modification that Lennart made
7 ** to port to 32 bit world and modify this file so that it
8 ** will be shared between platform.
9 ** 11/9/94 MCD Make MSW32 subset of MSW. Now MSW means
10 ** MicroSoft Window and MSW32 means the 32 bit worlds
11 ** of MicroSoft Window. Therefore you want the environment
12 ** to be MicroSoft Window and in the 32 bit world -
13 ** __MSW__ and __MSW32__ must be uncommented out.
14 ** 11/30/94 MCD Incorporated comments received for more
15 ** readability and the missing typedef for FLOAT.
16 ** 12/1/94 MCD Added PFVOID typedef
17 ** 5/1/95 MCD. Made many changes based on the inputs.
18 ** Changes:
19 ** 1) Rearrange the #ifdef so that there're definitions for
20 ** particular platforms.
21 ** 2) Took out the #define for computer and environment
22 ** that developer can uncomment
23 ** 3) Added __OLDCODE__ where the defines will be
24 ** obsoleted in the next version and advise not to use.
25 ** 4) Added the definitions for the following:
26 ** FILE_HANDLE, MEMORY_HANDLE, BOOL8,
27 ** MAX_INT8, MAX_INT16, MAX_INT32, MAX_UINT8
28 ** MAX_UINT16, MAX_UINT32, MAX_FLOAT32
29 ** 06/19/96 MCD. Took out MAX_FLOAT32
30 ** 07/15/96 MCD. Fixed the comments error
31 ** Add back BOOL8.
