Re: [julia-users] Re: get string from Cwchar_t in cfunction

[Samuel Colvin]

Ok, the "UTF32String(pointer_to_array(key, key_length, false))" method 
didn't work because the pointer was still Uint8, but when i changed it to 
be Int32 it worked.

So in summary i ended up with

function get_key(key_::Ptr{Int32}, key_length_::Ptr{Cint})
    key_length = unsafe_load(key_length_)
    UTF32String(pointer_to_array(key_, int64(key_length), false))
end

Working.

Thanks for the advice.
