/*! \brief Manages dynamic libraries.
|
|
*
|
|
* The Dynamic Library Manager provides a platform independent way to work with
|
|
* dynamic library. It load a specific dynamic library, and can returns specific
|
|
* symbol exported by the dynamic library.
|
|
*
|
|
* If an error occurs, a DynamicLibraryManagerException is thrown.
|
|
*
|
|
* \internal Implementation of the OS independent methods is in
|
|
* DynamicLibraryManager.cpp.
|
|
*
|
|
* \internal Porting to a new platform:
|
|
* - Adds platform detection in config/SelectDllLoader.h. Should define a specific
|
|
* macro for that platform of the form: CPPUNIT_HAVE_XYZ_DLL_LOADER, where
|
|
* XYZ is the platform.
|
|
* - Makes a copy of UnixDynamicLibraryManager.cpp and named it after the platform.
|
|
* - Updated the 'guard' in your file (CPPUNIT_HAVE_XYZ_DLL_LOADER) so that it is
|
|
* only processed if the matching platform has been detected.
|
|
* - Change the implementation of methods doLoadLibrary(), doReleaseLibrary(),
|
|
* doFindSymbol() in your copy. Those methods usually maps directly to OS calls.
|
|
* - Adds the file to the project.
