LDicomNet::SetSocketOptions

Summary

Sets the socket options used in a LDicomNet object. This feature is available in version 16 or higher.

Syntax

#include "ltdic.h"

L_INT LDicomNet::SetSocketOptions(pOptions)

Parameters

pDICOMSOCKETOPTIONS pOptions

Pointer to a structure that contains the options to used when creating a socket for DICOM communication.

Returns

Value	Meaning
SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.

Comments

This function is used to set options in the socket that will be created when calling LDicomNet::Connect on a LDicomNet object. Internally, the socket is created when calling LDicomNet::Connect. Therefore, LDicomNet::SetSocketOptions function should be called before calling LDicomNet::Connect.

For more information about sockets, see the MSDN Winsock documentation.
