Re: [Libexif-devel] Exif tag missing when loading a jpeg file on mips

[Pavan K. <pav...@gm...>]

Hi Jan, All
Pardon me for the naive question.
I see that most functions in exif-utils.c (such as exif_get_short() ) are
of type uintxx_t but they actually return value of type intxx_t (the
mentioned function internally calls exif_get_sshort)
Will this not cause undefined behavior?
For the problem I described, I suspect this to be an issue.
Any inputs will be much appreciated.

Regards
Pavan
