In order to install my aplication I use ExgDBRead() and it's
working.
Here is the code of the two callback (ReadProc() and DeleteProc())
functions that I used.
short ReadProc (void* dataP, unsigned long* sizeP, void* userDataP)
{
char szBuff[6];
short shType = htons( MSG_CS_INSTALL_APP_POCKET ); //
protocol convention
memcpy(szBuff, &shType, 2 ); //
memcpy(szBuff + 2, sizeP, 4 ); // I send to server the length of
data that
// this function
expects to receive
if ( 6 != WriteN( g_nSocket,(BytePtr) szBuff, 6 ) ) //send this to
server
{
return ERR_WRITE;
}
if ( 6 != ReadN( g_nSocket,(BytePtr) szBuff, 6 ) ) // read a
pocket send by server
{
return ERR_READ;
}
memcpy( &shType, szBuff, 2 ); //
shType = htons( shType ); //
//
if ( shType != MSG_SC_INSTALL_APP_POCKET ) //protocol
conventions
{ //
return ERR_TYPE //
} //
long lLen;
memcpy( &lLen, (szBuff + 2), 4 ); // in lLen is the lenght
of data that server actually
//send
*sizeP = htonl( lLen );
if ( *sizeP != ReadN( g_nSocket,(BytePtr) dataP, *sizeP ) ) //put
in dataP lLen bytes from
//prc file(received from server)
{
return ERR_READ;
}
return 0;
}
Notice that you must put 0 in sizeP after the file was transfered.
In my case the server do that. If you don't put 0, ExgDBRead() doesn't
notice that the transfer is over and it call ReadProc() in an infinite
loop.
In DeleteProc() I erased the previos version of aplication.
Please reply with this subject or else is very possible to not notice your
mail.
I hope I was clear enought, my english is not very good.
Best Regards
