EdmiError edmiRemoteGetHashedAttrInstanceBN(SdaiServerContext serverContextId,
SdaiModel modelId,
SdaiString entityName,
SdaiString attributeName,
SdaiString attrStringValue,
SdaiInteger attrIntegerValue,
SdaiInstance *instance,
SdaiInvocationId *edmiInvocationId);
Search the specified model for the instance with an attribute value equal to the specified attribute. If the instance is found, the function returns completion code equal to 0 and the instance id of the instance via the argument <instance>. If the instance is not found, the function returns completion code equal to 0 and 0 via the argument <instance>. This function can only return one instance value. Therefore this function should not be used if the persistent attribute hash table is not unique.If no attribute hash table is defined for the specified attribute, no sequential search is performed and the function returns an error code.
Arguments
