Member Function Documentation

virtual bool BLOCXX_NAMESPACE::SharedLibrary::doGetFunctionPointer ( const String functionName,
void **  fp 
) const [protected, pure virtual]

Derived classes have to override this function to implement the symbol loading.

The symbol to be looked up is contained in functionName, and the pointer to the function should be written into *fp. Return true if the function succeeded, false otherwise.

Parameters:
functionName The name of the function to resolve.
fp Where to store the function pointer.
Returns:
true if function succeeded, false otherwise.
template<class fptype >
bool BLOCXX_NAMESPACE::SharedLibrary::getFunctionPointer ( const String functionName,
fptype &  retval 
) [inline]

given a symbol name, getFunctionPointer will store a pointer to the function in retval.

If the symbol is found the function returns true, otherwise false. This function should be called like this: typedef ReturnType (*func_t)(param_t p1, ...); func_t theFunction; sharedLibrary->getFunctionPointer(sharedLibrary, "FunctionName", theFunction);

Parameters:
functionName The name of the function to resolve.
retval Will be set to the function pointer.
Returns:
true if function succeeded, false otherwise.
