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. + |
