L_LTDIC_API pDICOMIOD L_DicomFindIOD(pIOD, nCode, nType, bTree)
| pDICOMIOD pIOD; | /* pointer to a DICOMIOD structure */ | 
| L_UINT32 nCode; | /* code */ | 
| L_UCHAR nType; | /* type */ | 
| L_BOOL bTree; | /* flag that indicates how to evaluate the IOD structure */ | 
Returns a pointer to an item in the IOD Structure that contains the IOD with the specified code and type.
| 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.
