UniqueMallocOwner_test Class Reference

Description

Test:

Verify automatic management of memory originally allocated by C malloc. This situation typically arises when some plain-C function returns results in a heap allocated buffer, requiring the client to care for proper clean-up. To avoid creating a liability, we wrap the buffer into a smart pointer, which acts as ownership token and abstracts the specifics of clean-up.

This test places a given (or random) string into a heap malloced buffer, and then pushes the "hot potato" of ownership responsibility around; another function checks the content of the buffer and consumes the token as a side-effect. At the end, there should be no memory leak and the ownership token should be empty.
