Comments

This function is used together with any of the following functions:

L_DicomCreatePrivateCreatorDataElement

L_DicomFindFirstPrivateCreatorDataElement

L_DicomFindNextPrivateCreatorDataElement

To create private elements in a DICOM data set. For more information on private elements, see L_DicomCreatePrivateCreatorDataElement function.

Use this function with an existing private creator data element to create private elements. If successful, argument *puTag will contain the next available unused tag that has been reserved by the private creator data element pointed to by argument pPrivateCreatorDataElement.

For example, suppose the following tags exist in a DICOM data set:

	(0017, 0012)	private creator data element
	(0017, 1200)	private element
	(0017, 1201)	private element
	(0017, 1205)	private element

After a successful call to the L_DicomGetNextUnusedPrivateTag function, *puTag will contains the value 0x00171202, which can be used with the L_DicomInsertElement function to add a new private element.
