class filesystem_error;		(filesystem TS)

An exception type thrown when errors are encountered.

Inheritance diagram

Member functions

(constructor)	constructs the error object (public member function)
path1path2	returns the paths that were involved in the operation that caused the error (public member function)
what	returns the explanatory string (public member function)
