EdmiError edmiRemotePutAttrsEx(SdaiServerContext serverContextId,
SdaiAppInstance instance,
SdaiInteger attributes,
SdaiAttr attributeIds[],
SdaiSelect attributeValues[],
SdaiOptions options,
SdaiInvocationId *edmiInvocationId);
Assigns values to one or more of the attributes of a specified instance. This operation is applicable only to Explicit attributes, not to Inverse or Derive attributes. The attributes are identified by their attributeIds.
Arguments
| Type | Name | Comment |
| SdaiServerContext | serverContextId | Context identification, from edmiDefineServerContext |
| SdaiAppInstance | instance | A numeric instanceID that uniquely identifies an instance in the remote EDMdatabase |
| SdaiInteger | attributes | The number of attributes for which to assign values. |
| SdaiAttr | attributeIds[] | A buffer of attributeIds. Each attributeId identify an attribute of the given instance for which a value is to be assigned. |
| SdaiSelect | attributeValues[] | A buffer of tSdaiSelect structures. Each structure must contain the value to assign to the corresponding attribute. |
| SdaiOptions | options | Currently not used. |
| SdaiInvocationId | edmiInvocationId | Currently not used. |
