I have got a question for the bit fiddlers among us:
I am loading some data from a streamfile and I have no clue how big things can get.
Strategy 1: I am allocating some memory (%alloc) and for every line extend the allocated memory (%realloc).
Strategy 2: I get one "big" block of memory and only do a reallocation if the data doesn't fit. (more work on my side)
Doesn't the system do strategy 2 under the hood already? If I allocate 100 bytes the system probably allocates a page (or so) and not only 100 bytes. So a realloc should not trigger another allocation of a whole page.?!
