hi,
i am new to this list, but i have been exposed to c++ with some
intensity and have benefitted greatly from the loki library provided by
Andrei Alexandrescu, author of Modern C++ Design. His class template
SmartPtr provides everything you'd ever want in a wrapper class, memory
management included.Also the library is completely free
<loki-lib.SF>
I hope this helps, because i plan to integrate some python stuff with c
++
best regards
