1. RAII wrapper above handle type 2. Mechanism that strips prefix from names of functions in given module. Those functions are available through opDispatch-based mechanism.

@safe

struct CWrap (

alias module_

string prefix

alias constructor

alias destructor

) {

import std.traits : Parameters, ReturnType;;

ReturnType!constructor handle;

this();

this(typeof(this) );

this(Parameters!constructor args);

~this();

template opDispatch(string f);

}

Constructors

this this(): Undocumented in source.
this this(typeof(this) ): Undocumented in source.
this this(Parameters!constructor args): Undocumented in source.

Destructor

module_: module with functions from which given prefix should be stripped
prefix: prefix that should be stripped from names of functions

Examples

import etc.c.curl;
alias Curl = CWrap!(etc.c.curl, "curl_easy_", (int _) => curl_easy_init(), curl_easy_cleanup);
auto c = Curl(0);
c.setopt(CurlOption.url, "https://dlang.org");
c.perform();
