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



 

NAME


       fclose - close a stream

 

SYNOPSIS


       #include 

       int fclose(FILE *fp);

 

DESCRIPTION






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

       The  behaviour  of  fclose() is undefined if the stream parameter is an
       illegal pointer, or is a descriptor already passed to a previous  invo-
       cation of fclose().

 

RETURN VALUE


       Upon  successful  completion 0 is returned.  Otherwise, EOF is returned
       and the global variable 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).
