Re^5: C types and SV's

DrHyde, since I'm not writing my own TIFF reader but calling the libtiff API, for example if I read data in from this function, which states:

The library attempts to hide bit- and byte-ordering differences between the image and the native machine by converting data to the native machine order. Bit reversal is done if the FillOrder tag is opposite to the native machine bit order. 16- and 32-bit samples are automatically byte-swapped if the file was written with a byte order opposite to the native machine byte order

do I have to worry about your concerns, or will Perl's pack/unpack be sufficiently general? Thanks.

Sounds like you should be OK, but to be on the safe side, I'd write some specific tests for this, and verify that files with both byte orders work on machines with both byte orders, and with both 32- and 64-bit native ints. You can outsource the testing to the CPAN-testers, of course.	[reply]
