Parameter Description
pIOD Pointer to a DICOMIOD structure that contains an item in the IOD Structure. A pointer to the item in the IOD Structure that contains the IOD with the specified nCode and nType will be returned.
nCode Code value that specifies the Information Object Definition. The information object may be a Class, a Module or a Tag. For lists of default values, refer to Data Element Tag Constants, IOD Class Constants, and IOD Module Constants.
nType The type of Information Object Definition you are working with. Possible values are:
  Value Meaning
  IOD_TYPE_CLASS [0x00] Class type Information Object Definition.
  IOD_TYPE_MODULE [0x01] Module type Information Object Definition.
  IOD_TYPE_ELEMENT [0x02] Element type Information Object Definition.
bTree Flag that indicates how the IOD Structure will be evaluated. Possible values are:
  Value Meaning
  TRUE Evaluate the IOD Structure as a tree.
  FALSE Evaluate the IOD Structure as a list.

Returns

!NULL

A pointer to a DICOMIOD structure that contains the item in the IOD Structure of the specified code and type.

NULL

An item with the specified code and type was not found.

Comments

The nCode and nType parameters must correspond. For example, if you specify IOD_TYPE_CLASS in nType, you must specify a value from the IOD Class Constants in nCode. If you specify some other value, the item will not be found in the IOD Structure.
