*** Major changes in libio for egcs:
|
|
|
|
* Better support for Linux.
|
|
|
|
* Dejagnu testsuite.
|
|
|
|
*** Major changes in libio version 2.7.0:
|
|
|
|
* The data representations of _IO_FILE and streambufs have been modified.
|
|
The layout of the jump-table table _IO_jumps_t has been re-arranged
|
|
to match that of a virtual function table of a streambuf. Therefore,
|
|
we no longer need a separate _IO_FILE::_jumps pointer; instead it can
|
|
be shared with the virtual function table pointer. In addition to
|
|
saving space, this also removes the overhead when double indirection
|
|
was needed, and there are many simplificatons (e.g. we no longer need
|
|
the builtinbuf class.
|
|
|
|
* The streambuf::uflow virtual has been added, to match the standard.
|
|
|
|
* The ifstream, ofstream, and fstream classes now include the filebuf
|
|
as a member, rather than being pointed to it. Various related changes.
|
|
|
|
* Version number changed to generally follow libg++ (and gcc).
|
|
|
|
*** Major changes in libio version 0.66 (released with libg++ 2.6.1):
|
|
|
|
* Some documentation and an example in iostream.texi on how to derive
|
|
your own class from streambuf.
|
|
|
|
* New functions added to stdio: getline, detdelim, snprintf, vsnprintf.
|
|
This is for compatibility with the GNU C library.
|
|
|
|
*** Major changes in libio version 0.65 (released with libg++ 2.6):
|
|
|
|
* _IO_getline and streambuf::sgetline no longer write a '\0' at the end.
|
|
|
|
* A number of improvements to get closer to the ANSI/ISO C++ working
|
|
paper, such as:
|
|
- Added (preliminary support for) new ANSI streambuf::uflow virtual.
|
|
- Added istdiostream and ostdiostream classes.
|
|
- Added ostream::operator<<(bool) and istream::operator>>(bool&).
|
|
|
|
* More robust (and faster) initialization and cleanup of standard streambufs.
|
|
|
|
* Many small bug fixes, portability improvements, and random enhancements.
|
|
|
|
*** Major changes in libio version 0.63 (released with libg++ 2.5.3):
|
|
|
|
* There is a g++ bug that causes inconsistent name mangling for the
|
|
assembler name of the virtual function table for the istream class.
|
|
A work-around has been put into streambuf.h, which will make g++
|
|
always do the right thing. Note that this may require you to
|
|
recompile programs that were incorrectly compiled by g++.
|
|
|
|
* Functions that do printf-style formatting to the unbuffered
|
|
streams have been optimized to write to a temporary buffer.
