H5::Exception::Muter RAII dontPrint() wrapper

HDF5 Library C++ Users' Group

I’m pretty new to the C++ HDF5 library, but… any thoughts whether something like this quickie would be worth adding to the code base? Simple but not obvious to newbies.

/** Instantiating this class invokes H5::Exception::dontPrint(). Old settings
 * revert after leaving scope. For example:
 *
 *     void my_func()
 *     {
 *         H5::Exception::Muter muter;
 *         // ... do stuff with dontPrint() on ...
 *     } // Exception printing reverts to previous status on exit.
