I want to make a delegate of blocking I/O statement and pass it to a
function. Then it will be called immediately. This delegate never
escapes its creation scope, so I don't want heap closure allocation.
Will compiler create dynamic closure (e.g. with allocation) or static
closure (with pointer to the stack)?
void recv(ubyte[] buf, out size_t len)
{
// block until data is received
}
int numWaiters;
// will that "scope" enforce static closure?
void wait(scope void delegate() dg)
{
numWaiters++;
dg();
numWaiters--;
}
void test()
{
ubyte[] buf = new ubyte[1500];
size_t len;
wait( { recv(buf, len); } );
}
