[Libexif-devel] Error handling

[Joerg H. <jo...@de...>]

Hi

I've just doing some review especially on error handling when doing malloc
and realloc. I think it's not good to declare lot of functions as "void"
and in case of an error just do a "return;" in that case you canot detect
errors and behave respectivly.

I prefer a to replace at least some void-functions with (signed) int with a
standard return value of 1; if an error happens, they will return something
!= 1 (normally < 1).

This will probably produce at lot more if(function()) constructs, but I
think it's worth.

What do you think about that?
