Namespace: HDF.PInvoke

Assembly: HDF.PInvoke.dll

Syntax

public delegate System.Int32 operator_t(System.Int64 location_id, IntPtr attr_name, ref H5A.info_t ainfo, IntPtr op_data);

Parameters

Type	Name	Description
System.Int64	location_id	The location identifier for the group or dataset being iterated over
IntPtr	attr_name	The name of the current object attribute.
H5A.info_t	ainfo	The attribute’s info struct
IntPtr	op_data	A pointer referencing operator data passed to iterate

Returns

Type

Description

System.Int32

Valid return values from an operator and the resulting H5Aiterate2 and op behavior are as follows: Zero causes the iterator to continue, returning zero when all attributes have been processed. A positive value causes the iterator to immediately return that positive value, indicating short-circuit success. The iterator can be restarted at the next attribute, as indicated by the return value of n . A negative value causes the iterator to immediately return that value, indicating failure. The iterator can be restarted at the next attribute, as indicated by the return value of n .
