[edit] Parameters
| p | - | path to examine |
| ec | - | error code to modify in case of error |
[edit] 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.
[edit] Exceptions
The overload that does not take a std::error_code& parameter throws filesystem_error on underlying OS API errors, constructed withp as the first argument and the OS error code as the error code argument. std::bad_alloc may be thrown if memory allocation fails. 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. This overload has noexcept specification:
noexcept
