L_DicomSetMaxCommBlockLengthISCL

#include "ltdic.h"

L_LTDIC_API L_UINT32 L_DicomSetMaxCommBlockLengthISCL(hNet, nCommBlockLength)

Sets the maximum communication block length that can be sent/received by the current entity.

Parameters

HDICOMNET hNet

Handle to an existing DICOM Network. This is the handle returned from the L_DicomCreateNet function.

L_UINT32 nCommBlockLength

Size of the communication block length.

Returns

Value	Meaning
DICOM_SUCCESS	Success. The maximum communication block length was set. During mutual authentication, the client and server will agree to use the smaller communication block size of the two.
DICOM_ERROR	An error occurred. This usually occurs if the nCommBlockLength was too small for the maximum standard packet size (168 bytes). Refer to Return Codes.

Comments

An ISCL communication block contains a 32-byte header, followed by data, if data is included.

Please note that the size of the ISCL packets is 32 bytes larger than the communication block length, because of the header.
