[edit]

Defined in header`<experimental/filesystem>`
bool is_empty(const path& p);	(1)	(filesystem TS)
bool is_empty(const path& p, error_code& ec);	(2)	(filesystem TS)

Checks whether the given path refers to an empty file or directory.

The second version returnsfalse and setsec to an appropriate error code if an error occurs. Otherwise,ec is cleared with a call toec.clear().

[edit]Parameters

p	-	path to examine
ec	-	error code to modify in case of error

[edit]Return value

true ifp refers to an empty file or directory,false otherwise.

[edit]Exceptions

1)filesystem_error if an error occurs. The exception object is constructed withp as an argument. The error code is set to an appropriate error code for the error that caused the failure.
