Thanks for the help...
Actually I´m using C++ and the examples that I must have seen should be in C
and by the way, where I said that was the 3rd I meant the 4th line in the
example, sorry and the casting is done at the MemHandleLock like you said,
and not at the MemHandleNew ;) ...
Thanks again...

Assunto: RE: Casting?
Renato,
Are you using C++ ? C++ is much more picky about what syntax it will accept
and what it will do for you without asking. You are correct that casting
the result to a Char * is the thing to do. However, don't cast the
MemHandle. Many people do this even when using C, which normally doesn't
mind doing the conversion for you.
So, the code you should use is (possibly without the verbose comments):
// declare a handle to some memory
MemHandle testHandle;
// declare a pointer to Char
Char* ptext;
// get a handle on some memory
testHandle = MemHandleNew (12);
// lock it down, cast it to Char*, and assign the address to ptext
ptext = (Char *) MemHandleLock( testeHandle );
If this isn't clear to you, then either you should consult a book on C
and/or C++, or else perhaps I should have written even more comments. :)
