Member Function Documentation

SharedLibrary * SharedLibraryManager::load	(	const std::string &	name,
		int	openFlags = 0
	)			[virtual]

Attempts to load/initialize the given shared library, optionally specifying the given open flags to the platform-dependent loader.

SharedLibraries are reference-counted, so if the specified library is already loaded, the a second copy of the wrapper SharedLibrary will be returned and the reference count will be incremented accordingly.

Returns:

a SharedLibrary wrapper on success or NULL on failure

Definition at line 15 of file SharedLibraryManager.cpp.

bool SharedLibraryManager::unload

(

const std::string &

name

)

[virtual]

Decrements the reference count on the given shared library. The library will only be unloaded once no more references to it exist.

Returns:

true on successful decrement, false otherwise

Definition at line 35 of file SharedLibraryManager.cpp.

bool SharedLibraryManager::isLoaded

(

const std::string &

name

)

const [virtual]

Returns:

whether or not the given library is currently loaded with respect to this manager.

Definition at line 46 of file SharedLibraryManager.cpp.

void * SharedLibraryManager::getSymbol

(

const std::string &

symbol

)

[virtual]

Searches all shared libraries that are currently loaded for the given symbol.

Returns:

the handle of the shared library containing the given symbol or NULL if the symbol could not be found

Definition at line 50 of file SharedLibraryManager.cpp.

std::string SharedLibraryManager::getLastError

(

)

[virtual]

Returns:

a human-readable string describing the last error which occurred within this SharedLibrary

Definition at line 64 of file SharedLibraryManager.cpp.
