Dear Development team,
I've tasked at my workplace, to use libidn. I've found some minor
issues with the library
1, the idn-free function (in idn-free.h) misses the EXTERN "C"
- -qualifier, so when I included in the C++, I've get a link error. My
workaround was to include the file with extern "C", but I think it
isnt the preferable way, because all other header in the library do
not need this. I've understand the comaplaints about the idn_free, but
our production enviroment requires cross platform compatible code, so
normal free is not an option for us.
2, all of the idna_* function return int value, but the idna_strerror
takes the Idna_rc enum type as it's input parameter, so I've to
static_cast the return value. This can easily avoided if the function
returns Idna_rc instead of int. (And it will improve code quality as well)
I hope that my suggestion will improve libidn!
