L_LTDIC_API L_INT EXT_FUNCTION L_DicomSetSocketOptions(hNet, pOptions)
| HDICOMNET hNet; | /* a DICOM Network handle */ | 
| pDICOMSOCKETOPTIONS pOptions; | /* pointer to a structure */ | 
Sets the socket options used in an hNet network handle.
| Parameter | Description | 
| hNet | A DICOM Network handle. This is the handle returned from the L_DicomCreateNet function | 
| pOptions | Pointer to a structure that contains the options to used when creating a socket for DICOM communication. | 
Returns
| DICOM_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 the L_DicomConnect function on an hNet network handle. Internally, the socket is created when calling the L_DicomConnect function. Therefore, the L_DicomSetSocketOptions function should be called before calling the L_DicomConnect function.
For more information about sockets, see the MSDN Winsock documentation.
