Command to display std::experimental::filesystem::is_empty manual in Linux: $ man 3 std::experimental::filesystem::is_empty

NAME

std::experimental::filesystem::is_empty - std::experimental::filesystem::is_empty

Synopsis

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 returns false and sets ec to an appropriate error code if an error occurs. Otherwise, ec is cleared with a call to ec.clear().

Parameters

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

Return value

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

Exceptions

1) filesystem_error if an error occurs. The exception object is constructed with p as an argument. The error code is set to an appropriate error code for the error that caused the failure.
2)
noexcept specification:
