vformat

Syntax

native vformat(buffer[], len, const fmt[], vararg);

Description

Replacement for format_args. Much faster and %L compatible.
This works exactly like vsnprintf() from C.
You must pass in the output buffer and its size,
the string to format, and the number of the FIRST variable
argument parameter. For example, for:
function (a, b, c, ...)
You would pass 4 (a is 1, b is 2, c is 3, et cetera).
There is no vformatex().
