Wouldnt it be better to, rather than use a qemu_malloc() that is utterly
counterintuitive in that it has no way to report failure, and behaves in
ways people dont expect, to use normal malloc() and never pass it 0 ?
It's not that it doesn't have a way to report failure, it's that it
doesn't fail. Do you prefer functions that fail and report it to
functions that don't fail?
Seriously, who does that anyway? why call malloc when you dont want the
space? so you can use realloc? 99.99% of the time realloc() is the Wrong
Solution(tm).
Read the beginning of the thread. Basically it's for arrays, malloc(n *
sizeof(x)).
stick to what people know, and LART them for misuse of it if necessary.
The LART is a crash, great.
