Non-member functions

swap(std::basic_filebuf) (C++11)

 

virtual ~basic_filebuf();

Calls close() to close the associated file and destructs all other members of basic_filebuf. If an exception occurs during the destruction of the object, including the call to close(), it is caught and not rethrown.

Notes

Typically called by the destructor of std::basic_fstream.

Defect reports

The following behavior-changing defect reports were applied retroactively to previously published C++ standards.

DR	Applied to	Behavior as published	Correct behavior
LWG 622	C++98	it was unclear how to handle the exception thrown during destruction	it is caught but not rethrown
