Greets,
I added this line to the soldier program from the Inline C cookbook.
use Inline Config => BUILD_NOISY => 1;
... and I exposed a bunch of warnings. Here's one:
Soldier_396a.xs: In function `get_name':
Soldier_396a.xs:27: warning: cast to pointer from integer of
different size
This is the offending line of code:
return ((Soldier*)SvIV(SvRV(obj)))->name;
My guess is that this is happening because sizeof(IV) is 8 bytes on
my system, but memory addressing uses 32 bits. So the IV is overkill.
[begin excerpt from perlguts]
What is an "IV"?
Perl uses a special typedef IV which is a simple signed integer type
that is guaranteed to be large enough to hold a pointer (as well as
an integer). Additionally, there is the UV, which is simply an
unsigned IV.
[end excerpt from perlguts]
I believe that the warning is harmless, but I'd like to get rid of
it. I have twenty or thirty such lines in
Search::Kinosearch::KSearch::ResultSet, and it would be nice if it
compiled cleanly.
Possible?
