2000-08-22 Bruce Guenter <bruce@bruce-guenter.dyndns.org>
* Added the missing accessor for the internal "errnum" data member
to the fdibuf and fdobuf classes.
2000-08-10 Bruce Guenter <bruce@bruce-guenter.dyndns.org>
* fdibuf.cc (read_large): Fixed a bug in the increment of data.

into variables.
2000-04-08 Bruce Guenter <bguenter@bguenter.pointsnorth.com>
* fdibuf.cc (read_large): Fixed bug: count needed to be
incremented after reading data in.
2000-04-07 Bruce Guenter <bguenter@bguenter.pointsnorth.com>
* fdobuf_signed.cc (operator<<): Immediately output a '-' for
negative numbers rather than storing a negative flag for later.
* fdobuf_unsigned.cc (operator<<): Moved the integer versions of
this operator into their own modules.
* fdobuf_seek.cc (seek): Moved this routine out of fdobuf.cc
* fdibuf.cc (read_large): Added this routine to read in a chunk of
data larger than the size of the buffer.
2000-04-06 Bruce Guenter <bguenter@bguenter.pointsnorth.com>
* fdibuf_netstring.cc (getnetstring): Moved this routine into its
own source file.
* fdobuf.cc (write_large): Added this routine to write out a chunk
of data larger than the size of the buffer, to avoid doing extra
copies.
(write): Removed an extraneous code segment.
* fdobuf.h: Moved the fdobuf declarations here.
* fdibuf.h: Moved the fdibuf declarations here.
* fdbuf.h: Removed extraneous fdobuf declaration.
1999-07-08 Bruce Guenter <bguenter@mikhail.qcc.sk.ca>
* fdobuf.cc (write): Optimized this routine better for the case
where the amount of data to be written will fit inside the buffer.
1999-07-05 Bruce Guenter <bguenter@mikhail.qcc.sk.ca>
* fdbuf.h (fdobuf,fdibuf): Made some of the routines here virtual
in order to extend it properly.
Added "tell()" operations to both fdibuf and fdobuf to indicate
the current logical read/write point.
1999-07-04 Bruce Guenter <bguenter@mikhail.qcc.sk.ca>
* fdobuf_chownmod.cc: Added two new routines chown and chmod,
which operate directly on the open fd.
1999-06-30 Bruce Guenter <bguenter@mikhail.qcc.sk.ca>
* fdibuf_mystring.cc (getline): Make this routine return the
number of bytes actually read, including the delimiter, even
though the delimiter is not added to the returned string.
1999-06-29 Bruce Guenter <bguenter@mikhail.qcc.sk.ca>
* fdibuf.cc (fdibuf): Added a 'seekfwd' function to seek forwards
"o" bytes.
* fdibuf_mystring.cc (getline): Added locking and set the count
properly.
1999-06-28 Bruce Guenter <bguenter@mikhail.qcc.sk.ca>
* fdibuf.cc (get): Make sure count is set for get.
1999-06-06 Bruce Guenter <bguenter@mikhail.qcc.sk.ca>
* fdbuf.cc (fdbuf): Fixed long-standing bug -- I forgot to delete
the buffer in the destructor.
(close): Modified the code to ensure that the fd is not closed
twice (as would happen when destructing the fdbuf).
1999-05-31 Bruce Guenter <bguenter@mikhail.qcc.sk.ca>
* fdobuf.cc: Redefined flush as nflush; added sync code to nflush;
made flush and sync call nflush; added mutex lock calls to all
public methods.
* fdibuf.cc: Added mutex lock calls to all public methods.
* fdbuf.cc: Added debugging implementations of lock() and unlock()
mutex operators (to be removed before real use).
1999-05-28 Bruce Guenter <bguenter@mikhail.qcc.sk.ca>
* fdobuf.cc (fdobuf): Fixed missing initialization of bufpos in
one of the two constructors.
1999-05-01 Bruce Guenter <bguenter@mikhail.qcc.sk.ca>
* fdobuf.cc (fdobuf): Added an optional "mode" parameter which
defaults to 0666, which is the permissions for the new file.
(sync): Wrote this function to fsync the file descriptor.
1999-04-27 Bruce Guenter <bguenter@mikhail.qcc.sk.ca>
* fdbuf.h (fdobuf): Removed definition for sync and nonblock mode,
as they won't be handled correctly in the writing code.
1999-04-03 Bruce Guenter <bguenter@mikhail.qcc.sk.ca>
* fdobuf.cc (operator<<): Wrote an operator for signed and
unsigned longs, with overloaded functions for ints and shorts that
promote the parameters to longs.
(write): Wrote a write routine specifically for a single
character.
1999-04-01 Bruce Guenter <bguenter@mikhail.qcc.sk.ca>
* fdobuf.cc: Fixed handling of seek by adding a "bufpos" indicator
that points to the current position in the buffer at which writes
should go. buflength is effectively the maximum value of bufpos
between flushes.
* fdibuf.cc (get): Renamed getchar to get (to be potentially
overloaded with other types).
* fdbuf.h (fdbuf): Removed a bunch of write methods and replaced
them with "operator<<", with similar capability to iostreams
methods of the same names.
* fdobuf.cc (endl): Wrote this manipulator to write an end-of-line
and flush the buffer.
1999-03-31 Bruce Guenter <bguenter@mikhail.qcc.sk.ca>
* fdobuf_mystring.cc: Moved all the mystring-specific code from
fdobuf.cc into this module to lessen link problems.
* fdibuf_mystring.cc: Moved all the mystring-specific code from
fdibuf.cc into this module to lessen link problems.
* fdobuf.cc (seek): Wrote this seek routine to allow movement in
an output file buffer.
* fdibuf.cc (seek): Generalized the rewind routine to allow
arbitrary seeks. It also checks to see if the seek point is
within the current buffer and if so just repositions its
pointers.
* fdbuf.h: If BUFSIZE is not defined, set it here to 4096.
(class fdbuf ): Rename length, start, and size to buflength,
bufstart, and bufsize. Add a new field "offset" to indicate the
current file seek offset.
