ISO15765_TransmitMessage Method - intrepidcs API
C/C++ declare - VB.NET declare - C# declare -  Parameters - Return Values - Remarks - C/C++ example - VB.NET example - C# example

This method transmits a message using ISO15765-2 on a CAN network.  icsneoISO15765_EnableNetwroks must be called before using icsneoISO15765_TransmitMessage.  PCI bytes and Flow control decoding is taken care of by the dll for the transaction.

C/C++ Declare

void _stdcall icsneoISO15765_TransmitMessage(void * hObject, unsigned long ulNetworkID,stCM_ISO157652_TxMessage *pMsg,unsigned long ulBlockingTimeout);
 

Visual Basic .NET Declare

Public Declare Function icsneoISO15765_TransmitMessage Lib "icsneo40.dll" (ByVal hObject As IntPtr, ByVal ulNetworkID As Integer, ByRef pMsg As stCM_ISO157652_TxMessage, ByVal ulBlockingTimeout As Integer) As Int32

C# Declare

[DllImport("icsneo40.dll")]
 public static extern Int32 icsneoISO15765_TransmitMessage(IntPtr hObject,Int32 ulNetworkID,ref stCM_ISO157652_TxMessage pMsg,Int32 ulBlockingTimeout);



Parameters

hObject
    [in] Handle which specifies the driver object created with the OpenPort method. 

ulNetwork
    [in] Specifies the network to transmit the message on. See NetworkID List for a list of valid Network ID values. Network support varies by neoVI device. NETID_DEVICE transmits on to the neoVI Device Virtual Network (see users manual).

stCM_ISO157652_TxMessage
    [in] This is the address of the stCM_ISO15765_TxMessage structure. The structure contains the properties for the multi frame message transaction. 

ulBlockingTimeout
    [in] Amount of time in ms to wait for flow controls before timing out. 


Return Values

None. 

Remarks

None.
