Hi,
In Linux kernel programming, there are some parts that are not
allowed to sleep (to be rescheduled). For example: interrupt
handlers, softirqs and tasklets.
Using functions that can sleep (for example: malloc, semaphores,
regular mutexes - unlike spin_locks, etc.) is forbidden inside
Well, then we're going to have to agree to disagree on that
one. While some
design decisions may have made more sense at the time they were
made or the
ultimate pros and cons may not have been clear at the time, I
think that zero-
terminated strings are one of the design decisions which was
tru
Won't some functions doing just what addRange() and
removeRange() do solve that kind of problem (if necessary)?
That means, forbidding the GC to scan some memory area for some
time?
Like their C++11 counterparts:
void declare_reachable(void* p); // the region of memory
starting at p

If you are interested in D read this first:

You can find there e.g.:

result points outside of the bounds of the garbage collected

So `p+=10;` is already "undefined behavior
Hi,
Reading about the C++11, I stumbled upon this:

(The data inside is not really what it should be, but that, at
least, is a debugging problem, not a segfault one).
Just to let you know that I did it. I was writing the good data
(as double), but it was my verification test that assumed it to
be int...
Now I corrected it and it works!

I should also add that I allocated my structure with:
(init)
s.filedesc = cast(File*)GC.calloc(1,File.sizeof);
(open)
(*(s.filedesc)).open(*(cast(string*)arg),"w+b");
OMG! That solution works! Except that I was making a silly
mistake and thought that GC.alloc() prototype is similar to C's

Yes.

OK, I converted into using the std.stdio.File. Without success,
the programs till crashes.
However, in the meantime:
A) why there is no parameter-less constructor for std.stdio.File?

std.file is more about files and directories, not file
contents. I've abandoned std.stream.File some time ago. I just
use std.stdio.File partly because stdio, stdout, and stderr are
of that type anyway. It works with ranges as well.

Thank you. But why do I lose access to my std.stream.File file?
Somehow, the variable gets unallocated, thus the file is closed
back?
With pointers of C it used to be so simple... variable remained
allocated untel the corresponding free().
I do not quite grasp this (a bit) awkward mix betwee
I should at that the "__gshared" attribute was added in distress,

Hi all,
I am trying to port some application based on a library called
mediastreamer2, part of linphone software.
The basic software component built on top of mediastreamer2 is
called a "filter".
Basically, it is a C structure with parameters and some methods
(pointers to functions). Am
