to_char_ptr() std::unique_ptr< char[]> to_char_ptr ( const std::string &  str ) Copy a std::string into a std::unique_ptr<char[]>. Internally 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. See also CStrArray for multiple strings Example To call some function f(char *) with a string s, do: f(to_char_ptr(s).get());
