mydata is an auto variable, which goes out of scope when myfunction()
exits. *_mydata ends up pointing to garbage.
I'm not completely sure, but i think this can be solved by using:
static char mydata[16];
(Btw.: I don't know why you use char ** _mydata, i would use
char * _mydata, but then again, i'm not very familiar with
ctypes)
