/** @mainpage The official homepage is on: - http://marc.waeckerlin.org/computer/c_/mrw-c_/index The minimal runtime package (for use with VideoreKorder): Minimalpaket (für den VideoreKorder): - @PACKAGE_NAME@-minimal-@PACKAGE_VERSION@-1.i586.rpm More downloads see @ref downloads. All features are listed on the "Modules" page. @section intro Introduction Featureful C++ Library containing a lot of needful things. Everything, I often need, but it's missing in C++ standard libraries and other common 3rd party libraries, such as log4cxx, cppunit and boost. I have paid attention to define simple and a nice to use interfaces. The library makes use of object orientation, operator overload and templates, where it makes sense. The library passes several module tests before each delivery. It is therefore stable and tested. @section support Supported Platforms The library is generic UNIX, but should also work on Windows. It is sporadically tested on Windows in Cygwin. Stack trace works on Linux only, it could theoretically work on Sun Solaris too, but this is untested. Stack trace without symbol resolution, just getting the raw addresses, only depends on GNU gcc and should work on all platforms. Feedback is welcome! @section features Missing a Feature, Found a Bug? You are missing a feature, or an implementation is too incomplete for the purpose you need it? Or you even found a bug? Just ask me and I'll try to help you!

Link to the library with option @c -lmrw (or @c -lmrw-mt if your program is multi threaded), e.g.: @verbatim g++ -g -o myprogram myprogram.cxx -lmrw @endverbatim For the @ref AutoTools "unexpected handler" you need to link to @c -lmrwexcstderr or @c -lmrwexclog4cxx (or @c -lmrwexcstderr-mt or @c -lmrwexclog4cxx-mt if your program is multi threaded). For the @ref AutoFunctionTrace "automated function trace" you need to link to @c -lmrwautofunctiontracelog4cxx (or @c -lmrwautofunctiontracelog4cxx-mt if your program is multi threaded). In addition, you must compile and link your program with the GNU compiler specific option @c -finstrument-functions */ /** @page threads Thread Safety There is a severe bug in the g++ compiler with version >= 3.4: The macro @c _REENTRANT is always set and cannot be used to check whether we are in a multithreaded compilation or not! See http://gcc.gnu.org/bugzilla/show_bug.cgi?id=11953 for more details. Workaround: To enable multithreading, you must pass the @c -D_MT compiler flag for the GNU gcc verions 3.4 and above! To enable thread safety, you must link to @c libmrw-mt instead of @c libmrw. That means, your link option is: @c -lmrw-mt For GNU gcc verions 3.4 and above, you must use the compile option @c -D_MT in addition, because of a severe bug in the compiler. Different instances of classes can run in different threads, but instances of classes can not be shared between different threads. All classes are not thread safe, that means they should either always be accessed from the same thread, or you are responsible for locking. All methods are threads safe, that means, they can be called at the same time from different threads. But not on the same object. This means: One instance should only be used within one single thread. Different instances of the same class can be accessed simultaneousely in different threads. If you need more thread safety as a feature, please send me an email and ask me for it (you find the address in the package or on my personal homepage: http://marc.waeckerlin.org). */ /** @page libversion Library Versioning The library and the package have the same version number. This means, if you for example install the package versioned mrw-c++-2.6.4.tar.gz, then it builds a shared library of the same version, named libmrw.so.2.6.4. The naming is version=MAJOR.MINOR.LEAST. What do the numbers mean:
MAJOR
If the major number is increased, then the backwards compatibility was broken. Either there was an incompatible change in the implementation, or in the interface, e.g. a change in method parameters, or even parts of the library have been removed.
MINOR
If the minor number changes, then it remains backward compatible. Either there was a minor change in the implementation or behavior of some features, a bigger bugfix, or new feature were added. A program linked to a previous library with smaller minor number still works, but a program linked to newer library with a higher minor number may not work with a library that has a lower minor number. This is a one way, backwards only compatibility.
LEAST
The least number is increased for small changes, bugfixes, changes in the documentation and so on. Except the bugs, changes in the least number are fully forward and backward compatible.
This means, programs linked to mrw-c++ version 2.6.4 will work with library version 2.6.3, also with version 2.6.5, or with version 2.7.1, but it won't work with version 2.5.4 nor with 1.1.3 nor with 3.1.4. You can see the version of the library by issuing the command @c what. */ /** @page license License @verbinclude COPYING */ /** @page readme Readme @verbinclude README */ /** @page install Installation @verbinclude INSTALL */ /** @page news News @verbinclude NEWS */ /** @page changes Change Log @verbinclude ChangeLog */ /** @brief the namespace for this library All classes and all functions (except global operators) are placed in this namespace.
