a problem about windows memory

[richi]

Hi everyone,

I am sorry, my english is not good!

I found a problem about memory. In a function I malloced more memory than
before
that is 4.5625Kb in theory. Then I watched the memory size of the function
in Linux and
Unix through the command of "ps". After comparing with the early memory
size of
the function which didn't have change, I found the increaseded size was
different! In Linux and Unix
the size is about 4Kb, but in windows the size watched from task manager is
far more
than 4Kb.

can anyone help me and explain the phenomenon,plea se?

Probably under linux your memory is just reserved, not really allocated
until you try to use it. Under windows, probably more memory is
allocated right away.

Try asking on comp.unix.progr ammer. How the OS manages memory is
platform specific.

Probably under linux your memory is just reserved, not really allocated
until you try to use it. Under windows, probably more memory is
allocated right away.

Linux can do this, but Unix versions tend not to. The OP doesn't say
which one was used.

Re: a problem about windows memory

thank for your answer !
but I had tried hunderds of times, and the result is the same.
Under Linux and HP-Unix, the increased memory size was about 4Kb at all
times
But Under Windows the increased was not fixed, e.g. 4Kb, 8Kb, 16Kb.
I don't know why! Does it probably relate to the page size of operating
system?

Could be, try an OS group, you'll get more sense there.

Please explain how you can allocate 1/2 a byte. Either in practice
or in theory.

Please do not top-post. Your answer belongs after (or intermixed
with) the quoted material to which you reply, after snipping all
irrelevant material. See the following links:

Why do you think the OP is claiming that? (4672 is exactly 4.5625Kb
using the usual computer meaning of K.)

There you are. I am old fashioned and old, and tend to use decimal
orientation. :-)
