toCharPtr() std::unique_ptr<char[]> Euclid::Cfitsio::toCharPtr ( const std::string &  str ) Convert a string to a unique_ptr<char[]>. Used to work around non-const correctness of CFitsIO: when a function expects a char * instead of a const char *, string::c_str() cannot be used. To call some function f(char *) with a string s, do: f(toCharPtr(s).get());
