int _fclose_r(struct _reent *<[reent]>, FILE *<[fp]>);
2000-02-17 20:39:52 +01:00
DESCRIPTION
If the file or stream identified by <[fp]> is open, <<fclose>> closes
it, after first ensuring that any pending data is written (by calling
<<fflush(<[fp]>)>>).
The alternate function <<_fclose_r>> is a reentrant version.
The extra argument <[reent]> is a pointer to a reentrancy structure.
2000-02-17 20:39:52 +01:00
RETURNS
<<fclose>> returns <<0>> if successful (including when <[fp]> is
<<NULL>> or not an open file); otherwise, it returns <<EOF>>.
PORTABILITY
<<fclose>> is required by ANSI C.
Required OS subroutines: <<close>>, <<fstat>>, <<isatty>>, <<lseek>>,
<<read>>, <<sbrk>>, <<write>>.
