Parameter:
EthCanHandle_p:
Instance Handle of the CAN-Ethernet Gateway
Return Values:
(see Section 7.3.3)
ETHCAN_SUCCESSFUL
ETHCAN_ERR_ILLHANDLE
ETHCAN_ERR_ILLPARAM
ETHCAN_ERR_HWNOINIT
ETHCAN_ERR_HWDISCONNECT_FAILD
ETHCAN_ERR_SAL
ETHCAN_ERR_IFBTP
ETHCAN_ERR_RESOURCE
Note:
The function EthCanDeinitHardware() needs to be called as many
times, as the function EthCanInitHardware() was called previously
and returned without error. If the functions were called in „ Non-
blocked Mode “ it is important to be sure in any case that before
ending the application the disconnect has been signaled via the
Callback function.
Application Example:
Both application examples below show the use of the function with a
blocking and non-blocking call.
Blocking call
#define IP_ADDR ((192 << 0)+(168 << 8)+ (10 << 16)+(111 << 24))
#define IP_PORT (8234)
void main ( void )
{
DWORD dwRetcode;
tEthCanHandle EthCanHandle;
tEthCanHwParam EthCanHwParam;
EthCanHwParam.m_IpAdress = IP_ADDR;
EthCanHwParam.m_wPort = IP_PORT;
EthCanHwParam.m_UsedProtocol = kUseTCP;
