Hi, What precautions we need to take while writing 32 bit programs for 64 bit machines? Specifically, how can I take care of data type size differences between user space and kernel space?
In my program long integer is 4 bytes in user space. But when I pass a pointer to a long integer as an argument to a system call, kernel accesses 8 bytes using that pointer as size of long integer it is 8 bytes in kernel space. Regards, Vijay
