problem 1:
Prefix_clearError(Visession vi);
1:when does customer application call this function?
2: the purpoe is to clear error code and error description .
where is the error code? does it live in customer application?
3: where is the error description ?does it live in IVI-C driver program ?
problem 2:
how to deal with the first parameter in Prefix_init function?
the initializing function is Prefix_init(ViRsc Resource, ViBoolean Reset,ViSession * vi)
the first parameter is a string . but my driver is a IVI-C custom driver.
what string should be passed to the function ?
problem 3:
according to section 5.16.1 in IVI3-1 , Separate sessions should be used for both class driver and specific driver.
class initilize function should return class session;
application call Get Specific Handle to get specific driver session.by doing so, application can call other specific function.
however ,my driver is a custom driver .it should not incorporate interchangeability .In this case how to comply with section 5.16.1?
