Can something similar to &x=&y be accomplished in C

["Jim Stapleton" <stapleton.41@xxxxxxxxx>]

Lets say I'm iterating through an array, and I have a lot of
operations on the array needed to alter it...

int p = {1, 2,3,4 ...};
for(int i = 0; i < length_of_p; i++)
{
  some_op(p+i);
}

void some_op(int *t)
{
  /*do stuff with/to t*/
}

In C++ I could simply do int &t in the function, and it'd be fine, but
in C I have to use a pointer, which means a lot of dereferencing. Is
there any way to efficiently have the same effect as &x = &y (having a
variable "be" another variable, rather than just point to it) in plain
C with GCC, or is that out of the question?

Thanks,
