Searched the specified model for the instance id of the instance where the specified attribute has exact the specified value. If the attribute type is of string type use the attrStringValue to specify the attribute value. If the attribute type is of integer type, use the attrIntegerValue to specify the attribute value. This function returns only one instance id which implies that you only should use this function if the attribute value is defined to be unique. If the attribute value may occur in more than one instance, use edmiGetHashedAttrInstances. If no attribute hash table is defined for the specified attribute, no sequential search is performed and the function returns an error code.

Arguments

Type	Name	Comment
SdaiModel	modelId	A numeric modelID that uniquely identifies the model of interest in the EDMdatabase. The modelID is returned from the functions: sdaiCreateModel , sdaiCreateModelBN , sdaiOpenModelBN , edmiGetModel , edmiGetModelBN , sdaiGetInstanceModel
SdaiEntity	entityId
SdaiAttr	attrId	A numeric attributeID that uniquely identifies an attribute definition instance in the EDMdatabase. The attributeID is returned from the sdaiGetAttrDefinition and sdaiGetAttrDefinitionBN functions.
SdaiString	attrStringValue	is used to specify the hash table key for hash tables of SdaiString data type.
SdaiInteger	attrIntegerValue	is used to specify the hash table key for hash tables of SdaiInstance, and EdmPackedDate data types.
SdaiInstance	*instance	Address of the variable where to return the instance id of the found instance.

Return Value
