Namespace:
You mean like this? ---- void foo(T)(extern(C) void function(T*) func) { } ----That prints: Error: basic type expected, not extern
In theory that's correct, in practice the compiler refuses that, it's in Bugzilla, so try to define the type outside the signature (untested):
alias TF = extern(C) void function(T*);
void foo(T)(TF func) {}
