Hello,
how can I assign a void pointer to a structured pointer in a ROOT session?
When I do below and try to get the
variables declared in the structure, it gives me crazy numbers; I am using
an external library (libmonitor.so,
libshift.so) to load the file and first I must load (the library, very
first) the file and get its start point by a void pointer
-this is the only way in my case- after that I must assign it to a variable
that has embedded structure like that :
...
// headers are included, *.so files are loaded
struct DATEevent { // embedded structure
struct eventHeaderStruct header; // ordinary structs
struct equipmentStructMy payload;
};
void* ptr;
struct DATEevent* event;
// here, make the pointer 'ptr' point the start of file in memory
event = (struct DATEevent*)ptr;
printf("%08x \n",event->payload.whatever.whatever.array[5]); // which is a
specific number like da1e5afe
...
When I use this in an ordinary c++ source it is working. What is the problem
with this code ?..
Thank you.
