@file
@brief This file declares functions to convert exceptions to MySQL
error messages.
The pattern for use in other functions is:
@code
try
{
something_that_throws();
}
catch (...)
{
handle_foo_exception("function_name");
}
@endcode
There are different handlers for different use cases.
*/
/**
Handle an exception of any type.
Code that could throw exceptions should be wrapped in try/catch, and
the catch block should raise a corresponding MySQL error. If this
function is called from the catch block, it will raise a specialized
error message for many of the std::exception subclasses, or a more
generic error message if it is not a std::exception.
@param funcname the name of the function that caught an exception
@see handle_gis_exception
