FCLOSE(3)               NetBSD Library Functions Manual              FCLOSE(3)


NAME

     fclose -- close a stream


LIBRARY

     Standard C Library (libc, -lc)


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 indicate the error.  In either case
     no further access to the stream is possible.


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).


SEE ALSO

     close(2), fflush(3), fopen(3), setbuf(3)


STANDARDS

     The fclose() function conforms to ANSI X3.159-1989 (``ANSI C89'').
