Following up on my own post. You can avoid some casts.
This is also an example of how pulling a thread can lead
somewhere more complicated. :)
%z should work portably for size_t and should avoid a cast.
libdl already has this in libdl/rtl-shell.c which tries to provide a
C99 inttypes.h like constant.
if defined(__moxie__)
#define PRIdoff_t PRIo32
#else
#define PRIdoff_t PRIo64
#endif
Unfortunately, there is something similar defined in
testsuites/psxtests/include/pmacros.h which looks to be
better done.
Searching in cpukit for similar code turns up a number of
other types and repetitions.
grep -r "#define PRI" . | grep -v PRIORITY | grep -v PRINT
I would suggest the more elegant solution for the PRI constant
off_t, time_t, and mode_t would be
cpukit/include/rtems/inttypes_extensions.h
and that the best of all the duplicated definitions be moved there.
That centralizes them and them everyone uses the same ones.
I suspect that many of the remaining printf format warnings can then
be resolved using these helpers or by adding more.
This idea needs a review and approval by at least one other
developer. Especially the file name.
