As Im not too accuantied with palm developing thats the way i often
do things, i mean, by carefully checking each function documentation,
problem is in this case the answer is not there. Id have really liked
to read something like this there, where it should be, in the API
documentation. Something like:
'This functions returns a handle that can be locked/unlocked but
NEVER freed'
