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