Each execution of a diver function should be checked if it was
successful. For this purpose there is the function
Get_Error
.
Immediately after the execution of the function, the internal error
variable of the driver is set to the actual status.
This variable is available to the user program via the function
Get_Error
, so that a reaction to this error message can occur.
The investigation of the error variable is possible until a new
execution of a driver function has occurred. Then the error status of
the new function call is set.
