Checks if the given file status or path corresponds to a FIFO or pipe file.
1) Equivalent to s.type() == file_type::fifo.
2) Equivalent to is_fifo(status(p)).
3) Equivalent to is_fifo(status(p, ec)). Returns false and sets ec to an appropriate error code if an error occurs. Otherwise, ec is cleared with a call to ec.clear().
Parameters
| s | - | file status to check |
| p | - | path to query |
| ec | - | error code to modify in case of errors |
Return value
true if the given path or file status corresponds to a FIFO file.
