edmiUnsetProtectedAttrBN
- Former user (Deleted)
EdmiError edmiUnsetProtectedAttrBN(SdaiAppInstance appInstance,
SdaiString attributeName);
Unsets a protected attribute.Some system models are created and maintained by EDM and therefore the users need no write access to them. However, in these system models, some attributes may still be manipulated by selected users even if the model it self is open for read only. The ordinary operations such as e.g sdaiPutAttr and sdaiUnsetAttr, would return an error code if used on these attributes. To manipulate protected attributes one must use the protected-versions of the operations.
Arguments
| Type | Name | Comment |
| SdaiAppInstance | appInstance | A numeric instanceID that uniquely identifies the instance of interest in the EDMdatabase. |
| SdaiString | attributeName | The name of the protected attribute of interest. |
