It also returns if interrupted by a signal.
When an error occurs, of if it is interrupted by a signal, this

@subsection SRFI-28 - Basic Format Strings
@cindex SRFI-28
SRFI-28 provides a basic @code{format} procedure that provides only
the @code{~a}, @code{~s}, @code{~%}, and @code{~~} format specifiers.
You can import this procedure by using:
@lisp
(use-modules (srfi srfi-28))
@end lisp
@deffn {Scheme Procedure} format message arg @dots{}
Returns a formatted message, using @var{message} as the format string,
which can contain the following format specifiers:
@table @code
@item ~a
Insert the textual representation of the next @var{arg}, as if printed
by @code{display}.
@item ~s
Insert the textual representation of the next @var{arg}, as if printed
by @code{write}.
@item ~%
Insert a newline.
@item ~~
Insert a tilde.
@end table
This procedure is the same as calling @code{simple-format} (@pxref{Writing})
with @code{#f} as the destination.
