&qt;s Character string char

and all C format specifications ending with one of diouxXfeEgGcs, with
ARGUMENTs converted to proper type first. Variable widths are handled.
e.g. &qt;ooo&qt;&qt; = an octal number, &qt;xhhh&qt;&qt; = a hex numberThe format is a character string which contains three types of objects:

Plain characters, which are simply copied to standard output,
Character escape sequences, which are converted and copied to standard output,
Format specifications, each of which causes printing of the next successive argument.
The format is reused as necessary to consume all of the arguments. If the format requires more arguments than are supplied, the extra format specifications behave as if a zero value or null string, as appropriate, had been supplied.

The return value is zero on success, non-zero on failure.
