Howdy,
I have a native library set up, and I'm having some intermittant hangs. I
have a routine that sets up a structure and returns a pointer to the
structure back to the java program. This pointer is then stored in an int
java variable. It is then passed to other native functions as an argument,
and derefrenced to retrieve the struct.
First off, am I doing this in a reasonable way? How are C routines supposed
to allocate memory that will be only used by other C routines? is it safe
to return pointers back to the java side, or will the garbage collector
interfere with the memory that the C code created?
thanx for any tips!
