rv is an octave string of the returned bytes. This is a natural format for REG_SZ data; however, if the registry data was in another format, REG_DWORD then the calling program will need to process them

code is the success code. Values correspond to the codes in the winerror.h header file. The code of 0 is success, while other codes indicate failure In the case of failure, ’rv’ will be empty
