# std::filesystem::is_empty

From cppreference.com
< cpp‎ | filesystem

Defined in header `<filesystem>` |  |
bool is_empty( const std::filesystem::path& p ); bool is_empty( const std::filesystem::path& p, std::error_code& ec ); |  | (since C++17)

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

### Parameters

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

### Return value

true if the file indicated by `p` or if the type indicated `s` refers to an empty file or directory, false otherwise. The non-throwing overload returns false if an error occurs.

### Exceptions

The overload that does not take a std::error_code& parameter throws `filesystem_error` on underlying OS API errors, constructed with `p` as the first path argument and the OS error code as the error code argument. The overload taking a std::error_code& parameter sets it to the OS API error code if an OS API call fails, and executes ec.clear() if no errors occur. Any overload not marked `noexcept` may throw std::bad_alloc if memory allocation fails.
