| FUNCTION |
| <<fcloseall>>---close all files |
| |
| INDEX |
| fcloseall |
| INDEX |
| _fcloseall_r |
| |
| ANSI_SYNOPSIS |
| #include <stdio.h> |
| int fcloseall(void); |
| int _fcloseall_r (struct _reent *<[ptr]>); |
| |
| TRAD_SYNOPSIS |
| #include <stdio.h> |
| int fcloseall() |
| |
| int _fcloseall_r (<[ptr]>) |
| struct _reent *<[ptr]>; |
| |
| DESCRIPTION |
| <<fcloseall>> closes all files in the current reentrancy struct's domain. |
| The function <<_fcloseall_r>> is the same function, except the reentrancy |
| struct is passed in as the <[ptr]> argument. |
| |
| This function is not recommended as it closes all streams, including |
| the std streams. |
| |
| RETURNS |
| <<fclose>> returns <<0>> if all closes are successful. Otherwise, |
| EOF is returned. |
| |
| PORTABILITY |
| <<fcloseall>> is a glibc extension. |
| |
| Required OS subroutines: <<close>>, <<fstat>>, <<isatty>>, <<lseek>>, |
| <<read>>, <<sbrk>>, <<write>>. |
