How much memory does a call to 'malloc' allocates? – Daniel Lemire's blog
- tj-teej 2y agoI went to UIUC for CS ('14), in our Systems class we had one project where we had to write our own version of malloc() in C. They made it into a competition and it was so much fun (graded on latency and efficient space usage). I remember the person who won was a PhD student who had to take the undergrad course as a prereq for some Grade level class.
- floutist44 2y agoI loved this class, I graduated one year before and placed in the top 3. Everyone in the top has figured out that the test cases did a bunch of malloc(1) to screw up our memory layout but never tested it, so anything requesting a single byte we all had our code ignore it and return a bogus address immediately. Had they fixed this in the following year?
