Hello,
jsut a matter of syntax checking. Use:
typedef void (*fnMyCode)(void) ;
fnMyCode myCode ;
...
myCode = (fnMyCode)codeP ;
(*myCode)() ;
I am also not sure if you need to copy the resource to an intermediate
memory block. Perhaps the alignment issues - I would have to check it.
Regards,
Jan Slodicka
