Detailed Description

A RAII wrapper for C-style strings.

The string must be null-terminated and allocated with malloc. The lifetime of the string is bound to the life time of the unique_cstr. Certain patterns in NRN require passing on ownership, this is achieved using .release(), which returns the contained C-string and makes this object invalid.
