i try to compile the following slightly modified sample from the book and it failed with the following messages

======= source ============

import std.stdio;
import std.concurrency;

void fileWriter()
{
	// Write loop
	for (bool running = true; running; )
	{
		receive(
			(immutable(ubyte)[] buffer) {},
			(OwnerTerminated) { running = false; }
		);
	}
	stderr.writeln("Normally terminated.");
}

void main()
{
	
}

====== error messages =======

/Users/ruslan/Source/dlang/dub-test/source/listener.d(11): Error: template std.concurrency.receive does not match any function template declaration. Candidates are:
/usr/local/Cellar/dmd/2.063.2/libexec/src/phobos/std/concurrency.d(646):        std.concurrency.receive(T...)(T ops)
/Users/ruslan/Source/dlang/dub-test/source/listener.d(11): Error: template std.concurrency.receive(T...)(T ops) cannot deduce template function from argument types !()(void function(immutable(ubyte)[] buffer) pure nothrow @safe, void)

========================

what's wrong? if i replace OwnerTerminated with int or simply remove everything is ok.

if i replace with my own struct Terminate - fail.

any help would be appreciated.

Hi Ruslan,

This is a template function literal taking an argument named "OwnerTerminated", not a function with an unnamed parameter of type OwnerTerminated. Quite a sublime trap, admittedly.

In the future you might want to post similar questions to the digitalmars.D.learn group instead.

Hope this helps,
