CONFORMANCECALLBACK Function

#include "ltdic.h"

L_BOOL pEXT_CALLBACK YourFunction(pElement, nFlags, pUserData)

pDICOMELEMENT pElement;	a DICOM handle
L_UINT16 nFlags;	flag that indicates any errors
L_VOID * pUserData;	pointer to additional data

Processes each Data Element of the Data Set to determine conformance.

Parameter	Description
pElement	A DICOM handle.
nFlags	Flag that indicates errors associated with the Data Element. Possible values are given below and may be combined using the bitwise OR ( \| ) operator.
	Value	Meaning
	CALLBACK_ERROR_UNKNOWN_CLASS	[0x0001] Error- improper class code.
	CALLBACK_ERROR_UNKNOWN_TAG	[0x0002] Error - improper tag value.
	CALLBACK_ERROR_UNKNOWN_VR	[0x0004] Error - unknown Value Representation code.
	CALLBACK_ERROR_WRONG_VR	[0x0008] Error - incorrect Value Representation code.
	CALLBACK_ERROR_MIN_VM	[0x0010] Error - improper minimum value multiplicity value.
	CALLBACK_ERROR_MAX_VM	[0x0020] Error - improper maximum value multiplicity value.
	CALLBACK_ERROR_DIVIDE_VM	[0x0040] Error - improper value multiplicity divisor.
	CALLBACK_ERROR_IMAGE	[0x0080] Error - improper image.
	CALLBACK_ERROR_ELEMENT	[0x0100] Error - improper element.
pUserData	Void pointer that you can use to access a variable or structure containing data that your callback function needs. This gives you a way to receive data indirectly from the function that uses this callback function. (This is the same pointer that you pass in the pUserData parameter of the L_DicomConformanceDS function.)
	Keep in mind that this is a void pointer, which must be cast to the appropriate data type within your callback function.

Returns

TRUE	The Data Set comforms to the standard.
FALSE	The Data Set does not comform to the standard.

Comments

The L_DicomConformanceDS function calls your callback function to verify each Data Element in the DataSet.

The purpose of this callback function is just to verify that the data provided in the Data Set conforms to the standard.

Set nFlags with the appropriate error message for any inconsistency encountered. For example, if a Data Element has a Value Representation of VR_FD (Floating Point Double) and the Value Field has an integer value, set the CALLBACK_ERROR_VR error in nFlags and return False.
