Memory allocation

Hi All,

What ur suggestion on following…

Writing a NDIS miniport driver… Want to allocate shared memory
for receive buffers( total= 4096, size= 1536 bytes each ).

Should I allocate it at once i.e. size of 4096*1536 bytes OR
should I allocate individually 1536, 4096 times.

What generally you guys do in such cases?

Thanks in adavance

any way …
but go for contiguous allocation. you can trverse systematically.

At once.
Common buffers (called “shared memory” by NDIS) are page-sized, so, allocating 4096 common buffers is a huge waste of memory for unused tails.

Where are you allocating it? Application? Anyway you want. Kernel?

Now that takes some discussion and an idea of what you want to do.
