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 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 behaviour. ERRORS
EBADF The filedescriptor 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). 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, e.g. with sync(2) or fsync(2). CONFORMING TO
The fclose function conforms to ANSI X3.159-1989 (``ANSI C''). SEE ALSO
close(2), fcloseall(3), fflush(3), fopen(3), setbuf(3) BSD MANPAGE

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''). BSD
