| *** 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. |
