Defined in header <filesystem>
bool is_other( std::filesystem::file_status s );	(1)	(since C++17)
bool is_other( const std::filesystem::path& p ); bool is_other( const std::filesystem::path& p, std::error_code& ec );	(2)	(since C++17)

Checks if the given file status or path corresponds to a file of type other type. That is, the file exists, but is neither regular file, nor directory nor a symlink.

1) Equivalent to exists(s) && !is_regular_file(s) && !is_directory(s) && !is_symlink(s).

2) Equivalent to is_other(status(p)) or is_other(status(p, ec)), respectively.

Parameters

s	-	file status to check
p	-	path to examine
ec	-	error code to store the error status to

Return value

true if the file indicated by p or if the type indicated s refers to a file that is not regular file, directory, or a symlink, false otherwise. The non-throwing overload returns false if an error occurs.

Exceptions

2) 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 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
