I am reading the OpenSL documentation for Android. Quoting the following document: http://mobilepearls.com/labs/native-android-api/ndk/docs/opensles/ "Callback handlers should be prepared to be called more or less frequently, to receive additional event types, and should ignore event types that they do not recognize. Callbacks that are configured with an event mask of enabled...
c++,function,pointers,namespaces,ampersand
Do these lines mean the same? Both works without any warning messages! int (*pFunc)() = func1; // I learned this is right. int (*pFunc)() = &func1; // Works well with an ampersand too. Why do I have to put an ampersand in this case? Without it, doesn't work! int...

I'm using AmpersandJS and I'm trying to emulate the pod structure of Ember so that, instead of the typical folders-per-type structure: app |-- views |-- index.js |-- login.js |-- people.js |-- templates |-- index.jade |-- login.jade |-- people.jade you have folders-per-component instead: app |-- index |-- view.js |-- template.jade |--...
ruby,ampersand
The two lines in this code: p ["9", "6", "4"] p %w(9 6 4) return exactly the same array ["9", "6", "4"]. But the first line with map: p ["9", "6", "4"].map(&:to_i) works fine, and the second one: p %w(9 6 4).map{&:to_i} gives: syntax error, unexpected & p %w(9 6...
c++,function,pointers,constructor,ampersand

c++,return,bit-manipulation,ampersand
I'm not entirely sure what happens in this process and what the outcome would be. I've never come across using && in a return or especially a single one in the same return statement. bool myfunction(unsigned int x) { return x && !(x & (x - 1)); } I'd love...
