Thanks a ton for your reply.

1. Seems your g_main_loop_run will run many times. I am running it once
only and invoke g_main_loop_run and g_main_loop_unref* *when I am done. Am
I wrong? My g_main_loop_run runs in synchronous way so I start it in new
thread. Please see bold sentences below.
2. Can you please share your timeout_callback implementation.

3.
My code:

bool Connect( csui uiTimeoutInSecs, UtilError *pErr = NULL )
{

if ( !m_bInitialized )
{
 return ValidationError( "Client is not initialzed. Initialize before
connecting.", pErr );
}

if ( m_pAccount )
{
* // WILL COME here while reconnecting*
if ( purple_account_is_disconnected( m_pAccount ) )
 {
purple_account_set_password(m_pAccount, m_pPassword.c_str());
 purple_account_connect(m_pAccount);
if ( !WaitForSuccessfulConnection( uiTimeoutInSecs, pErr ) )
 {
return false;
 }

return true;
 }

if ( m_pAccount->disconnecting )
 return ValidationError( "Account is disconnecting. Make a connection after
a few moments.", pErr );
 }
 std::string strProtocol;
if( !ValidateProtocol( strProtocol, pErr ) )
 return false;

// Create the account
 m_pAccount = purple_account_new( m_pUserName.c_str(), strProtocol.c_str()
);
if( !m_pAccount )
 return ValidationError( "Account cannot be created for user", pErr );

 purple_account_set_password( m_pAccount, m_pPassword.c_str() );
 // It's necessary to enable the account first.
purple_account_set_enabled( m_pAccount, m_pUId.c_str(), TRUE );
 // Now, to connect the account(s), create a status and activate it.
 PurpleSavedStatus *pStatus = purple_savedstatus_new( NULL,
PURPLE_STATUS_AVAILABLE );
 if ( !pStatus )
return ValidationError( "Status for created account is NULL", pErr );

purple_savedstatus_activate( pStatus );
 // Register to libpurple callback signals
RegisterToSignals();


m_pLoop = g_main_loop_new(NULL, FALSE);

//if ( !m_thread.IsInitialized() )
//m_pLoop = g_main_loop_new(NULL, FALSE);
 #ifndef _WIN32
signal(SIGCHLD, SIG_IGN);
 #endif

                // *this runs g_main_loop_run in separate thread. If i
don't use separate thread my g_main_loop_run keeps running and I am not
able to              // proceed to next line*
 m_thread.Init( NULL, 0, StartGLoopAsync, m_pLoop, 0, NULL );

if ( !WaitForSuccessfulConnection( uiTimeoutInSecs, pErr ) )
 {
return false;
 }

return true;
 }

Once this Connect func returns true, I send message. This works fine but
reconnecting doesnt work.


Please respond. Thanks.
