FCLOSE(3)                                           Linux Programmer's Manual                                          FCLOSE(3)



NAME
       fclose - close a stream

SYNOPSIS
       #include <stdio.h>

       int fclose(FILE *fp);

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

RETURN VALUE
       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.

ERRORS
       EBADF  The file descriptor underlying fp 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).

CONFORMING TO
       C89, C99.

NOTES
       Note that fclose() only flushes 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).
