Member Function Documentation

void * CdcDynamicLibrary::GetFunctionByName

(

const CdcString &

func_name )

Returns a pointer to a function in the library.

It access the function by it's name. The caller must cast this pointer to the function pointer! If the function cannot be found in the library, or if the library cannot be loaded, GetFunctionByName will return NULL. The error message can be retrieved from GetLastError

Parameters:

func_name

The name of the function in the library.

Returns:

(void*) A pointer to this function as pointer to void.
