There is no law against using the CAPI to get arguments individually from
the tuple of args and disposing of them one at a time as desired.

Python strings are not only not resizeable they are IMMUTABLE. Your example
coding would likely cause great harm.
The easiest way to do this is make the string a part of the return:
fillinstring = cplusplusapp.read()

You can create the string in the C API using e.g. PyString_FromString.
