namespace Poco {
class Foundation_API SharedLibrary: private SharedLibraryImpl
The SharedLibrary class dynamically
loads shared libraries at run-time.
{
public:
SharedLibrary();
Creates a SharedLibrary object.
SharedLibrary(const std::string& path);
Creates a SharedLibrary object and loads a library
from the given path.
virtual ~SharedLibrary();
Destroys the SharedLibrary. The actual library
remains loaded.
void load(const std::string& path);
Loads a shared library from the given path.
Throws a LibraryAlreadyLoadedException if
a library has already been loaded.
Throws a LibraryLoadException if the library
cannot be loaded.
void unload();
Unloads a shared library.
bool isLoaded() const;
Returns true iff a library has been loaded.
bool hasSymbol(const std::string& name);
Returns true iff the loaded library contains
a symbol with the given name.
void* getSymbol(const std::string& name);
Returns the address of the symbol with
the given name. For functions, this
is the entry point of the function.
Throws a NotFoundException if the symbol
does not exist.
const std::string& getPath() const;
Returns the path of the library, as
specified in a call to load() or the
constructor.
static std::string suffix();
Returns the platform-specific filename suffix
for shared libraries (including the period).
In debug mode, the suffix also includes a
"d" to specify the debug version of a library.
