std::filesystem::is_other: std::filesystem::is_other

NAME

std::filesystem::is_other - std::filesystem::is_other

Synopsis


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 ); (2) (since C++17)
bool is_other( const std::filesystem::path& p, std::error_code& ec ) noexcept;


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.
