Usage

 
(import error-utils)

errorf

[procedure] (errorf [LOCATION] FORMAT [ARG ...])

Invoke error with a message built by the (error-format-procedure).

Should the argument list not match the criteria for a format argument list then the arguments are passed directly to error. The point being errorf will raise an error.

errorf-print

[procedure] (errorf-print [LOCATION] FORMAT [ARG...] [PORT (current-error-port)])

Displays a message like errorf but does not raise an error. Message is written to PORT.

error-print

[procedure] (error-print [ARG ...] [PORT (current-error-port)])

Displays a message like error but does not raise an error. Message is written to PORT.

*error-print

[procedure] (*error-print ARGS [PORT (current-error-port)])

A list version of error-print.

error-format-procedure

[procedure] (error-format-procedure [FORMAT]) => procedure

Parameter for the FORMAT procedure used by errorf. The default is the Unit extras format.

For I18N situations format format would be a better choice.
