= Variable Arguments =

''Part of'' StandardLibraryCategory

== Description ==

Use std.c.stdarg for variable arguments.

The std.c.stdarg module is now [http://www.digitalmars.com/pnews/read.php?server=news.digitalmars.com&group=digitalmars.D&artnum=4490 obsolete] with the release of DMD 0.93. Use std.stdarg instead (see VariableArgumentsUsingStdStdargExample).

== Example ==

{{{
#!d
import std.c.stdarg;


int foo(char *x, ...)
{
    va_list ap;

    va_start!(typeof(x))(ap, x);
    printf("&x = %p, ap = %p\n", &x, ap);

    int i;
    i = va_arg!(typeof(i))(ap);
    printf("i = %d\n", i);

    long l;
    l = va_arg!(typeof(l))(ap);
    printf("l = %lld\n", l);

    uint k;
    k = va_arg!(typeof(k))(ap);
    printf("k = %u\n", k);

    va_end(ap);

    return i + l + k;
}


void main()
{
    int j;

    j = foo("hello", 3, 23L, 4);
    printf("j = %d\n", j);
    assert(j == 30);
}
}}}
