perfomance, malloc, HeapAlloc

[Lloyd Dupont]

is there any performance difference between malloc() & HeapMalloc()?

is there any performance difference between malloc() & HeapMalloc()?

It depends on the implementation of malloc.

Generally malloc is an allocation mechanism on top of HeapAlloc that
provides optimisation by allocating a single large block and
sub-dividing it down more optimally than HeapAlloc. Additionally, a
debug malloc implementation may provide leak detection diagnostic
features.

[Tom Widmer [VC++ MVP]]

is there any performance difference between malloc() & HeapMalloc()?

In recent versions of VC, in the release version CRT, malloc delegates
almost directly to HeapAlloc, so the performance difference is negligable.
