+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>>.
