Searches the specified model for definitions of persistent attribute hash tables. For each hash table a structure of type tSdaiAttrHashTable (see below) is returned. If both entity name and attribute name are specified, information about a possible persistent attribute hash table for that attribute is returned. If only entity name is specified, information about all persistent attribute hash tables for that entity is returned. If not the entity name is specified, information about all persistent attribute hash tables for the entities with entity index equal or greater to the argument entityIndex are returned.

Arguments

Type	Name	Comment
SdaiModel	modelId	Instance Id that uniquely identifies a dictionaryModel or a dataModel in the EDMdatabase. The modelID is returned from the functions: sdaiCreateModel , sdaiCreateModelBN , sdaiOpenModelBN , edmiGetModel , edmiGetModelBN , sdaiGetInstanceModel
SdaiString	entityName	Optional. Specify the name of the instance type, i.e. the name of the entity that defines the instance type. Entity names are case insensitive.
SdaiString	attributeName	Optional. Specifies the name of the attribute. Attribute names are case insensitive.
SdaiInteger	*entityIndex	Optional. Used if entityName == NULL. Then it is the index of the first entity in the model, to search for persistent attribute hash tables.
SdaiInteger	*attrHashTables	Address of variable where number of attribute hash tables is returned.
SdaiAttrHashTable	*data	The address of array pointer to the tSdaiAttrHashTable array. After use the array must be released by edmiFree.
