L_DicomSetMaxCommBlockLengthISCL

#include "ltdic.h"

L_UINT32 EXT_FUNCTION L_DicomSetMaxCommBlockLengthISCL(hNet, nMaxCommBlockLength)

HDICOMNET hNet;	/* handle to an existing DICOM network */
L_UINT32 nMaxCommBlockLength;	/* maximum communication block length */

Sets the maximum communication block length that can be sent/received by the current entity. This function is available in the Medical Suite toolkits.

Parameter	Description
hNet	Handle to an existing DICOM Network. This is the handle returned from the L_DicomCreateNet function.
nMaxCommBlockLength	Size of the communication block length.

Returns

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 nMaxCommBlockLength 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.
