| bool is_fifo( file_status s ); | (1) | (filesystem TS) |

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().| Contents | 
[edit] Parameters
| s | - | file status to check | 
| p | - | path to query | 
| ec | - | error code to modify in case of errors | 
[edit] Return value
true if the given path or file status corresponds to a FIFO file.

noexcept specification:

  2) Throws filesystem_error if an error occurs. The exception object is constructed with 
p as an argument.[edit] See also
