We can check on the status of the PPP connection (active, inactive, opening or closing) using INETMGR_NetStatus().

NetState netState = NET_INVALID_STATE;

AEENetStats netStats;

netState = INETMGR_NetStatus (pINetMgr, &netStats);

We can use INETMGR_OnEvent() to monitor both the status of the PPP connection and socket connections. Refer to NetMgrEvent enum in AEENet.h for a list of all network and socket events.

// Register to receive Network and Socket events

INETMGR_OnEvent(piNet, (PFNNETMGREVENT)CheckNetStatus,

(void*)pMe, TRUE);

//Callback invoked when Network/Socket event is received

static void CheckNetStatus(void* cxt,

NetMgrEvent evt, uint32 dwData) {

SampleApp *pMe = (SampleApp*)cxt;

if(evt == NE_PPP) {

// network event. dwData = NetState enum value

// refer NetState data structure in BREW API Reference doc

}

if(evt == NE_SO_CLOSING || evt == NE_SO_CLOSED) {

// socket event - closing or closed.

// DwData is pointer to socket

}

… …

return;
