Question #249804 on Duetto changed:

Status: Open => Answered
Alessandro Pignotti proposed the following answer:
Hi Ben,
there is no specific API at the moment to do a copy-less conversion,
although we have plan to add it soon. In duetto 0.9.6 and the upcoming
1.0 release you can use the following hack to access a typed array like
a plain pointer:
Int8Array* ar=new Int8Array(4);
char* volatile c=(char*)(Array*)ar;
c[2] = 42;
Please be careful in using the right C data type for any given typed
array to guarantee correct results. The apparently useless double cast
is necessary. Again, we plan to add a cleaner solution in future, but
this should work and no copy is made.
