We aren't the best people to ask, being a special interest group who only
look at SCSI drivers, hardware &c. for the Linux operating system.
You need to understand the handling of character arrays and pointers in C
and C++ before attempting this; the languages don't provide support for
naive handling of character strings as unitary objects that can chucked
about willy-nilly directly, although standard string handling functions
(not including substr) are provided.
