Hi all, new to the forum. Glad to see it's as active as it is.
I'm starting off writing an experimental VPN client, and I want
to use the PalmVPPI.h (the 'VPN' prefs panel) interface to
configure it.
Is this a mistake? I've noticed that Mergic VPN sidesteps
the VPN prefs panel altogether. and don't provide
a 'Vppi', they just have a config 'appl', a 'libr', and a 'neti'
driver. It's occurred to me that they know something
I don't know about the Palm VPN infrastructure. :)
My immediate problem, however, is sort of fundamental.
When my 'Vppi' app gets a launch code of 'GetAccounts',
the cmdPBP is pointing to a structure of type VPNAccountType.
Fine. I can fill that in with my accounts, right?
My stumbling block is that it has a pointer (not array) member
called 'accounts', and I don't know what type of memory it's safe
to point it to. My first guess was that it would
be initialized to some "big-enough" space, and I could
just naiively fill that up. Well no.
Device resets on exit from PilotMain.
Next I tried a static inside my own app's space. Nope.
Device resets on exit from PilotMain.
So where else is there? Seems I shouldn't use MemPtrNew.
There are no init/cleanup launch codes, so who would MemPtrFree it?
Found nothing in the docs, headers, or samples about this.
Is there an implicit folklore S.O.P. for plugin panels
missing from my education? Any advice appreciated.
I'm debugging on a PalmTX over USB with the Palm OS Debugger.
