| 19 | FUNCTION |
---|
| 20 | <<fcloseall>>---close all files |

| 26 | |
---|
| 27 | SYNOPSIS |
---|
| 28 | #include <stdio.h> |
---|
| 29 | int fcloseall(void); |
---|
| 30 | int _fcloseall_r (struct _reent *<[ptr]>); |
---|
| 31 | |
---|
| 32 | DESCRIPTION |
---|
| 33 | <<fcloseall>> closes all files in the current reentrancy struct's domain. |
---|
| 34 | The function <<_fcloseall_r>> is the same function, except the reentrancy |
---|
| 35 | struct is passed in as the <[ptr]> argument. |
---|
| 36 | |
---|
| 37 | This function is not recommended as it closes all streams, including |
---|
| 38 | the std streams. |
---|
| 39 | |
---|
| 40 | RETURNS |
---|
| 41 | <<fclose>> returns <<0>> if all closes are successful. Otherwise, |
---|
| 42 | EOF is returned. |
---|
| 43 | |
---|
| 44 | PORTABILITY |
---|
| 45 | <<fcloseall>> is a glibc extension. |
---|
| 46 | |
---|
| 47 | Required OS subroutines: <<close>>, <<fstat>>, <<isatty>>, <<lseek>>, |
---|
| 48 | <<read>>, <<sbrk>>, <<write>>. |
