bool is_fifo() const;
bool is_fifo( std::error_code& ec ) const noexcept;
(since C++17)

Checks whether the pointed-to object is a FIFO or pipe file. Effectively returns std::filesystem::is_fifo(status()) or std::filesystem::is_fifo(status(ec)), respectively


[edit] Parameters

ec - out-parameter for error reporting in the non-throwing overload

[edit] Return value

true if the referred-to filesystem object is a FIFO or pipe file, false otherwise.

[edit] 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 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.
