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). | |
| 32 | Any allocated memory is | |
| 33 | .IR free 'd. | |
| 22f1f128 | 34 | .SH "SEE ALSO" |
| 639aed4c KB |
35 | close(2), fflush(3), fopen(3), free(3), setbuf(3) |
| 36 | .SH "RETURN VALUE" | |
| 37 | Upon successful completion 0 is returned. | |
| 38 | Otherwise, | |
| 22f1f128 | 39 | .B EOF |
| 639aed4c KB |
40 | is returned and the global variable |
| 41 | .I errno | |
| 42 | is set to indicate the error. | |
| 43 | In either case no further access to the stream is possible. | |
| 44 | .SH ERRORS | |
| 45 | .TP 15 | |
| 46 | [EBADF] | |
| 47 | .I Stream | |
| 48 | is not an open stream. | |
| 49 | .PP | |
| 50 | .I Fclose | |
| 51 | may also fail and set | |
| 52 | .I errno | |
| 53 | for any of the errors specified for the routines | |
| 54 | .IR close (2) | |
| 55 | or | |
| 56 | .IR fflush (3). | |
| 57 | .SH STANDARDS | |
| 58 | .I Fclose | |
| 59 | conforms to ANSI X3.159-1989 (``ANSI C''). |
