write_bin(f, bytes)

Input: f, bytes · Output: no output

What it is

The inverse of read_bin: writes raw bytes to f (file handle, opened writable/appendable). bytes is a Vec/List of numbers, every one of them a whole number in 0..=255 — anything else errors rather than being truncated into range.

Overloads

One call shape — this function is not overloaded.
