Determines whether one ore more attributes, identified by their attributeIds, of a specified instance, identified by its instanceId, are unset or have been assigned values. The attributeIds are specified in the input buffer argument <attributeIds>. A buffer with the same number of booleans will be returned in the argument <valueSet>. Any unset attributes will have their corresponding elements in the <valueSet> buffer set to sdaiFALSE. Likewise, if an attribute is set, i.e has been assigned a value, the corresponding <valueSet> buffer element will be set to sdaiTRUE.

Arguments

Type	Name	Comment
SdaiServerContext	serverContextId	Context identification, from edmiDefineServerContext
SdaiInstance	instanceId	A numeric instanceID that uniquely identifies the instance of interest in the remote EDMdatabase
SdaiVersion	version	The version of the edmModel to apply this function call on. The version argument is a sequence number counting from one by increments of one for each new model version created. A zero version number means the current version of the edmModel.
SdaiInteger	attributes	The number of attributeIds in the <attributeIds> argument.
SdaiAttr	attributeIds[]	A buffer containing all the attributeIds to be checked.
SdaiBoolean	valueSet	A variable that will receive a pointer to a buffer of SdaiBoolean elements. Each element describes the set/unset status of the corresponding attribute specified in the <attributeIds> argument.
SdaiInvocationId	edmiInvocationId	Currently not used.
