Whoa, this is probably a result of inertion. After programming for for X11 and MS Windows I couldn't imagine that a memory handle can be something different from a 32-bit integer!
Well, I wouldn't be surprised then if GCC doesn't complain either...

The problem line was: DmWrite( MemHandleLock( h ), 0, h2, size ); The third parameter to DmWrite is a "const void *". Since a MemHandle is defined as a "struct _opaque *" by the PalmTypes.h header, it converts silently into a const pointer to void, since both C and C++ allow any pointer to become a pointer to void (C++ disallows the other way). I don't think there is a way to get CodeWarrior to warn about this, since it is valid C. In a sense, it would be a lot better if MemHandle was defined as a 4-byte struct, since that can't silently convert to anything -- however, a struct like that wouldn't be able to be stored in a register as a temporary by the compiler due to the more complicated type. -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/tech/support/forums/ -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/tech/support/forums/
