24 | .SH DESCRIPTION |
| 25 | .I Fclose | |
| 639aed4c | 26 | dissociates the named |
| e6ecb2ae | 27 | .I stream |
| 639aed4c KB |
28 | from its underlying file or set of functions. |
| 29 | If the stream was being used for output, any buffered data is written | |
| 30 | first, using | |
| 31 | .IR fflush (3). | |

36 | is returned and the global variable |
| 37 | .I errno | |
| 38 | is set to indicate the error. | |
| 39 | In either case no further access to the stream is possible. | |
