Does QNX4 support a swap file?
|
| Solution |
No, it does not. There are no plans for implementing one in QNX4. The main reason for this is that reasons for requiring realtime response/performancs typically conflict with the reasons for requiring a swap file.
The requirement for swapping in most QNX4 applications is quite low. The efficiency of the OS and Watcom compiler provide relatively small processes in terms of memory requirements. When this is combined with the ability to share code between multiple process invocations and shared libraries, the memory demands for QNX are quite moderate. |
