i have two pointers

wchat_t *str and wchar_t * etr

srt is pointing to wchar_t type data like 11.22.11.22
and etr is also pointing to simlilar data. 12.32.14.32

Now i want to have a pointer which points to the (combined) data of both the pointers like this
wchar_t *stretr it should point to the 11.22.11.22 12.32.14.32

please tell me how to get this pointer?what operations are required on str and etr?

somthing like this is possible?
wchar_t join = str +' '+etr;
then make stretr points to join?
