Taken with modifications from std.process.execv:
import core.stdc.stdlib;
import std.string;
import std.stdio;
import std.conv;
const(char)** argsToC(in string[] argv)
{
auto _argv = cast(const(char)**)malloc((char*).sizeof * (1 + argv.length));
toAStringz(argv, _argv);
return _argv;
}
private void toAStringz(in string[] a, const(char)** az)
{
foreach(string s; a)
{
*az++ = toStringz(s);
}
*az = null;
}
void main()
{
string[] args = ["foo", "bla"];
auto _argv = argsToC(args);
assert(to!string(_argv[0]) == "foo");
assert(to!string(_argv[1]) == "bla");
}
Take a look at the various execv/execvp in std.process, but be careful
since most of them use alloca to allocate on the stack.
