An SDO upload (i.e., read) request.

◆ Signature
The signature of the callback function invoked on completion of an SDO upload request.
Note that the callback function SHOULD NOT throw exceptions. Since it is invoked from C, any exception that is thrown cannot be caught and will result in a call to std::terminate()
.
- Parameters
-
id | the node-ID. |
idx | the object index. |
subidx | the object sub-index. |
ec | the SDO abort code (0 on success). |
value | the value received from the SDO server. |
Definition at line 375 of file sdo.hpp.
