Thread-local storage can be created using the thread_local keyword. A variable declared with the thread_local specifier is said to have thread storage duration. Each thread in a program has its own copy of each thread-local variable. A thread-local variable with function (local) scope will be in...

Creates a path from a set of points [{x:?,y:?},{x:?,y:?},...,{x:?,y:?}] with rounded corners of radius. If the corner angle is too small to fit the radius or the distance between corners does not allow room the corners radius is reduced to a best fit. Usage Example var triangle = [ { x: 200...

Although package:listenv implements a list-like interface to environments, its performance relative to environments for hash-like purposes is poor on hash retrieval. However, if the indexes are numeric, it can be quite fast on retrieval. However, they have other advantages, e.g. compatibility with ...

Their names are of the form strtoX, where X is one of l, ul, d, etc to determine the target type of the conversion double strtod(char const* p, char** endptr); long double strtold(char const* p...

Here is a very simple example to illustrate how to write a NIF. Directory structure: nif_test ├── c_src │   ├── Makefile │   └── nif_test.c ├── rebar.config └── src ├── nif_test.app.src └── nif_test.erl This structure can be easily initialized using Rebar3: $ rebar3 new lib nif_...

Official documentation: http://erlang.org/doc/man/erl_nif.html The most important structs, types and macros of the Erlang C API are the following: ERL_NIF_TERM: the type for Erlang terms. This is the return type that NIF functions must follow. ERL_NIF_INIT(MODULE, ErlNifFunc funcs[], load, relo...

var client = new AmazonDynamoDBClient(); // Store item client.PutItem(new PutItemRequest { TableName = "Books", Item = new Dictionary<string, AttributeValue> { { "Title", new AttributeValue { S = "Cryptonomicon" } }, { "...

var client = new AmazonDynamoDBClient(); Table booksTable = Table.LoadTable(client, "Books"); // Store item Document book = new Document(); book["Title"] = "Cryptonomicon"; book["Id"] = 42; book["Authors"] = new List<string> { "Ne...

This example consists of two parts: first, we must define our Book type; second, we use it with DynamoDBContext. [DynamoDBTable("Books")] class Book { [DynamoDBHashKey] public int Id { get; set; } public string Title { get; set; } public List<string> Authors { ...

The Collections class provides a way to make a list unmodifiable: List<String> ls = new ArrayList<String>(); List<String> unmodifiableList = Collections.unmodifiableList(ls); If you want an unmodifiable list with one item you can use: List<String> unmodifiableList = Col...

The Collections class allows for you to move objects around in the list using various methods (ls is the List): Reversing a list: Collections.reverse(ls); Rotating positions of elements in a list The rotate method requires an integer argument. This is how many spots to move it along the line b...
