alias va_list;
The argument pointer type.

void va_start(T)(out va_list ap, ref T parmn);
Initialize ap. For 32 bit code, parmn should be the last named parameter. For 64 bit code, parmn should be _va_argsave.

T va_arg(T)(ref va_list ap);
Retrieve and return the next value that is type T. Should use the other va_arg instead, as this won't work for 64 bit code.

void va_arg(T)(ref va_list ap, ref T parmn);
Retrieve and return the next value that is type T. This is the preferred version.

void va_arg()(ref va_list ap, TypeInfo ti, void* parmn);
Retrieve and store through parmn the next value that is of TypeInfo ti. Used when the static type is not known.

void va_end(va_list ap);
End use of ap.
