Thinking about watching 'Read-Only Memory' without the hassle? Finding where to stream, rent, buy, or watch where to watch the Jonathan Asselin directed movie can be a bit of a headache so we at ...
The rationale is that it suffices to check that the pointer is located before the end of BSS and Read-only data to affirm the pointer in Static memory. So, my main question has two parts: to my understating, the latter approach above is silently assuming that, as random as the location of the heap might be, it comes after BBS and Read-only data - never in-between. Is that a safe assumption? if ...
Checking if a C/C++ pointer points to read-only memory during runtime ...
the "hello world" is actually stored in read-only memory. I am not so clear about read-only memory. What is the explanation? Is that like a flag to the compiler that tells the compiler to do not write into that section?
Not anymore. With the introduction of the read-only memory types, the call to Stream.WriteAsync(byte[]) is simply forwarding to the other overload, here. ... So, under the hood, everything is using the ReadOnlyMemory / ReadonlySpan types to marshal and access the bytes. Is there a drawback?
This is because only the first page of the shared memory buffer is read causing only a first touch on this page (so mapped in physical memory). Other pages are still left untouched and so they are only mapped in vritual memory and not physical memory.
