Hi!
I find code:
[code]
import c.stdlib;
import c.stdlib;
import std.outofmemory;
class Foo{
static void[] buffer;
static int bufindex;
static const int bufsize = 100;
static this(){
void *p;
p = malloc(bufsize);
if (!p)
throw new OutOfMemory;
gc.addRange(p, p + bufsize);
buffer = p[0 .. bufsize];
}
static ~this(){
if (buffer.length){
gc.removeRange(buffer);
free(buffer);
buffer = null;
}
}
new(uint sz){
void *p;
p = &buffer[bufindex];
bufindex += sz;
if (bufindex > buffer.length)
throw new OutOfMemory;
return p;
}
delete(void* p){
assert(0);
}
static int mark(){
return bufindex;
}
static void release(int i){
bufindex = i;
}
}
void test(){
int m = Foo.mark();
Foo f1 = new Foo; // allocate
Foo f2 = new Foo; // allocate
Foo.release(m); // deallocate f1 and f2
}
[/code]
When I try compile i have some error:[code]
vander@vander-VirtualBox:~/Pulpit/D$ gdc Memory.d -o Memory

When i comment import c.stdlib;
I have error
