Return to global_private.h CVS log

Up to [ls] / linuxsampler / src / common

* code cleanup:
- global.h now only covers global definitions that are needed for the C++
  API header files, all implementation internal global definitions are now
  in global_private.h
- atomic.h is not exposed to the C++ API anymore (replaced the references
  in SynchronizedConfig.h for this with local definitions)
- no need to include config.h anymore for using LS's API header files
- DB instruments classes are not exposed to the C++ API
- POSIX callback functions of Thread.h are hidden
- the (optional) gig Engine benchmark compiles again
- updated Doxyfile.in
- fixed warnings in API doc generation
* preparations for release 0.5.0
