L_INT EXT_FUNCTION L_DicomSetExtended(hPDU, nID, pData, nLength)

HDICOMPDU hPDU;	/* a DICOM Associate handle */
L_UCHAR nID;	/* presentation ID */
L_UCHAR *pData;	/* extended data */
L_UINT32 nLength;	/* length of the extended data */

Sets the extended data associated with the specified Presentation Context.

Parameter	Description
hPDU	A DICOM Associate handle.
nID	Presentation ID of the Presentation Context to which to set the extended data. The presentation ID provides information about both the class type of the data and the transfer syntax to use when transferring the data. It also identifies a specific Presentation Context within an Associate.
pData	Buffer that contains the data to set.
nLength	Length of pData.

Returns

0	SUCCESS
>0	An error occurred. Refer to Return Codes.
