| /****************************************************************************** |
| ** 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 - |
| ** __MSW__ and __MSW32__ must be uncommented out. |
| ** 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. |
