fclose(3)               Library Functions Manual               fclose(3)

ИМЯ

       fclose - close a stream

БИБЛИОТЕКА

       Standard C library (libc, -lc)

СИНТАКСИС

       #include <stdio.h>

       int fclose(FILE *stream);

ОПИСАНИЕ

       The fclose() function flushes the stream pointed to by stream
       (writing any buffered output data using fflush(3)) and closes the
       underlying file descriptor.

ЗНАЧЕНИЕ, ВОЗВРАЩАЕМОЕ ФУНКЦИЕЙ

       Upon successful completion, 0 is returned.  Otherwise, EOF is
       returned and errno is set to indicate the error.  In either case,
       any further access (including another call to fclose()) to the
       stream results in undefined behavior.

ОШИБКИ

       EBADF  The file descriptor underlying stream is not valid.

       The fclose() function may also fail and set errno for any of the
       errors specified for the routines close(2), write(2), or
       fflush(3).

ПРИМЕЧАНИЯ

       Note that fclose() flushes only the user-space buffers provided
       by the C library.  To ensure that the data is physically stored
       on disk the kernel buffers must be flushed too, for example, with
       sync(2) or fsync(2).
