Member Function Documentation

virtual bool OW_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. Implemented in OW_NAMESPACE::dlSharedLibrary.

template<class fptype> bool OW_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. Definition at line 67 of file OW_SharedLibrary.hpp.
