[comp.sys.dec] Help needed with mmap

time@oxtrap.UUCP (Tim Endres) (06/09/89)

We have a need to use mmap() to port our system to a Dec 3100.
I can successfully call mmap(), but it doesn't appear to work properly.
For example, it is called w/ MAP_SHARED, but it doesn't appear to be
updating the mapped file object, and other processes mapping the file
are not seeing the updates.

Unfortunately, our machine came loaded with no mmap() man page.

Also, does anyone know if 128K *is* the absolute limit for
SysV shmget() creation size?

Thanks, Tim Endres
