fclose(3)

NAME

       fclose - close a stream

SYNOPSIS

       #include <stdio.h>

       int fclose( FILE *stream);

DESCRIPTION

       The  fclose function dissociates the named stream from its
       underlying file or set of functions.  If  the  stream  was
       being used for output, any buffered data is written first,
       using fflush(3).

RETURN VALUES

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

ERRORS

       EBADF  The argument stream is not an open stream.

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

CONFORMING TO

       The fclose function conforms to ANSI  C3.159-1989  (``ANSI
       C'').
