L_LTDIC_API L_VOID L_DicomDeleteSignature(hDS, pSignatureItem)
Removes one or all Digital Signatures from the Data Set.
A DICOM handle.
Pointer to a DICOMELEMENT structure that specifies the Digital Signatures Sequence Item which corresponds to the Digital Signature to be removed from the Data Set. To remove all the Digital Signatures in the entire Data Set, set this parameter to NULL.
You can use this function to remove a single Digital Signature by specifying the corresponding Digital Signatures Sequence Item. The function will delete the specified Item from the Data Set. The Message Authentication Code (MAC) Parameters Sequence Item that was referenced by the deleted Digital Signatures Sequence Item will also be deleted if it is not referenced by a Digital Signatures Sequence Item anymore.
You can also use the function to remove all the Digital Signatures that exist in the Data Set by passing NULL to the function. In this case, all the MAC Parameters Sequence (4FFE,0001) and the Digital Signatures Sequence (FFFA,FFFA) Data Elements that exist in the Data Set will be deleted.
