Member Function Documentation

findSymbol()

void * inviwo::SharedLibrary::findSymbol

(

const std::string &

name

)

Get function address from library.

Example usage:

using f_getModule = InviwoModuleFactoryObject* (__stdcall *)();
auto moduleFunc = reinterpret_cast<f_getModule>(sharedLib->findSymbol("createModule"));

Parameters

name	Function name

Returns

Address to function if found, otherwise nullptr

findSymbolTyped()

template<typename T>

T inviwo::SharedLibrary::findSymbolTyped

(

const std::string &

name

)

Get typed function address from library.

Example usage:

using f_getModule = InviwoModuleFactoryObject* (__stdcall *)();
auto moduleFunc = sharedLib->findSymbolTyped<f_getModule>("createModule"));

Parameters

name	Function name

Returns

Address to function if found, otherwise nullptr

release()

void inviwo::SharedLibrary::release

(

)

Reset the handle and effectively leak the lib. Needed for some dll that crashes on exit otherwise
