From what I briefly read, it allocates used memory.  SO lets say you have an array, and you want to expand the array, in basic you would REDIM the array, with a new value, as in:

DIM A(1) REM variable A now has 1 storage space in its array.
....some code manipulates variable A and it needs more space......
REDIM A(5)
Now variable A can hold 5 values!  Remember when trying to access arrays, the count starts a 0, not 1!

I believe that is what realloc(ate) does.  Let me know if anyone comes to the same conclusion.
