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>>. */ /* This file based upon fwalk.c. */ #include <_ansi.h> #include <reent.h> #include <stdio.h> #include <stdlib.h> #include <errno.h> #include "local.h" int _DEFUN(_fcloseall_r, (ptr), struct _reent *ptr) { return _fwalk_reent (ptr, _fclose_r); } #ifndef _REENT_ONLY int _DEFUN_VOID(fcloseall) { return _fcloseall_r (_GLOBAL_REENT); } #endif
