Comments

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

LDicomDS::CreatePrivateCreatorDataElement

LDicomDS::FindFirstPrivateCreatorDataElement

LDicomDS::FindNextPrivateCreatorDataElement

to create private elements in a DICOM data set. For more information on private elements, see LDicomDS::CreatePrivateCreatorDataElement.

Use this method 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)

ß private creator data element

 

(0017, 1200)

ß private element

 

(0017, 1201)

ß private element

 

(0017, 1205)

ß private element

After a successful call to LDicomDS::GetNextUnusedPrivateTag, *puTag will contains the value 0x00171202, which can be used with LDicomDS::InsertElement to add a new private element.
