TCPIP_MAC_EVENT_RESULT PIC32MACEventInit(TCPIP_MAC_HANDLE hMac, int intPri, int intSubPri)
Summary:
Initializes the ethernet event notification.
Description:
This function initializes the ethernet event notification.
It performs any resource allocation that may be needed.
Precondition:
None.
Parameters:
hMac - parameter identifying the intended MAC
intPri - priority of the TCPIP interrupt events
intSubPri - sub-priority of the TCPIP interrupt events
Returns:
TCPIP_MAC_EVRES_OK if initialization succeeded,
an error code otherwise
Example:
<code>
PIC32MACEventInit( hMac, 4, 3 );
</code>
Remarks:
Not multi-threaded safe.
