Perhaps this will help: http://stackoverflow.com/questions/1195675/convert-a-char-to-stdstring
IIRC, something ike std::string return_string(pointer_to_const_unsigned_char_var); return_string is an std::string initialized to the value pointed to my the variable in the initializer. If you want the return_string to have more space, say to append to it, then you can do: std::string return_string(pointer_to_const_unsigned_char_var,????) // replace ???? with the size of the area to be allocated. ref: http://en.cppreference.com/w/cpp/string/basic_string/basic_string for the above, in the examples section. FWIW, I am not a C++ programmer. I have read up a bit on it, but found the above with a simple Google search. https://www.google.com/webhp?ie=UTF-8#q=C%2B%2B+std%3A%3Astring+cast On Tue, Aug 11, 2015 at 9:07 PM, Nicolas J?ger <jagernicolas at legtux.org> wrote: > Hi, > I have some basic problem, but I didn't found the solution so far... > maybe some people are using C++ and already deal with that problem : > > conversion from ?const unsigned char*? to non-scalar type ?std::string > > I got the `const unsigned char*` from `sqlite3_column_text()` and I > want to pass the result as a `std::string` parameter to a C++ function > > regards, > Nicolas J. > _______________________________________________ > sqlite-users mailing list > sqlite-users at mailinglists.sqlite.org > http://mailinglists.sqlite.org/cgi-bin/mailman/listinfo/sqlite-users > -- Schrodinger's backup: The condition of any backup is unknown until a restore is attempted. Yoda of Borg, we are. Futile, resistance is, yes. Assimilated, you will be. He's about as useful as a wax frying pan. 10 to the 12th power microphones = 1 Megaphone Maranatha! <>< John McKown
