seconds.
The default is 0, which means to wait without a time limit.

Don't treat Ctrl+C and Ctrl+D specially.
When this option is not specified, these characters interrupt getkey.

The message is used as a format string in
sprintf(3),
with a single argument, the number of seconds left.
Typical usage is therefore
"Press a key within %d seconds to ...".
If

contains other format string directives, the behavior is undefined and
getkey
may crash.
If there is no time limit specified, the number of seconds left is reported as 0.
