I've been working on a (NeXT) application that makes a fair amount of
use of memory-mapped files (map_fd(), vm_*()), and although it runs
fine, the compiler gives a dismaying number of warning messages. Most
of these have to do with conversions between pointers and "vm_offset_t".
I have been just casting and assigning; the system doesn't seem to mind
the puns. However, the compiler moans, which makes me think there must be
an "approved" way, such as "ptr_to_vm_offset()" ( 1/2 =8) ). Similarly,
the function map_fd() (to map a file descriptor into virtual memory)
doesn't seem to be declared in any header files, so I get some more warnings
from that. I'm just wondering if anyone else has run across these same
problems and if so what did you do?
Any info appreciated ...
