TileDB provides an easy way to check for an error for every API call, as well as retrieve the error message. We provide a simple example in the code listing above. After compiling and running the program, you get the following output (<cwd> below stands for you current working directory path):

C++

$ g++ -std=c++11 errors.cc -o errors_cpp -ltiledb
$ ./errors_cpp
TileDB exception:
[TileDB::StorageManager] Error: Cannot create group; Group '<cwd>/my_group' already exists
Callback:
[TileDB::StorageManager] Error: Cannot create group; Group '<cwd>/my_group' already exists

Python

$ python errors.py
TileDB exception: [TileDB::StorageManager] Error: Cannot create group; Group '<cwd>/my_group' already exists

Note that if TileDB is built from source in debug and verbose modes, then the error messages will be printed to standard output even if you do not catch explicitly the error as shown above.
