L_DicomDelTransfer

Summary

Deletes a Transfer Syntax from the specified Presentation Context.

Syntax

#include "ltdic.h"

L_LTDIC_API L_VOID L_DicomDelTransfer(hPDU, nID, nIndex)

Parameters

L_UCHAR nID

Presentation ID. The presentation ID provides information about both the class type of the data and the transfer syntax to use when transferring the data.

L_INT nIndex

The index of the Transfer Syntax to delete.

Returns

None.

Comments

A DICOM Associate (Request or Accept) can have multiple Presentation Contexts. A DICOM Associate Request can have multiple Transfer Syntax entries for each Presentation Context. A Transfer Syntax can be deleted by specifying the ID for the appropriate Presentation Context and the index for the appropriate Transfer Syntax.
