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)])</procedure> 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)])</procedure> 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)])</procedure> A list version of {{error-print}}. ==== error-format-procedure <procedure>(error-format-procedure [FORMAT]) => procedure</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. ==== warning-on <procedure>(warning-on [PORT]) -> (#!rest -> void)</procedure> Returns a {{procedure}} displaying a warning message on the supplied {{PORT}}. ; {{PORT}} : {{output-port}} == Author [[/users/kon-lovett|Kon Lovett]] == Repository This egg is hosted on the CHICKEN Subversion repository: [[https://anonymous@code.call-cc.org/svn/chicken-eggs/release/5/error-utils|https://anonymous@code.call-cc.org/svn/chicken-eggs/release/5/error-utils]] If you want to check out the source code repository of this egg and you are not familiar with Subversion, see [[/egg-svn-checkout|this page]]. == Version history ; 2.1.0 : Add {{warning-on}}. ; 2.0.2 : . ; 2.0.1 : . ; 2.0.0 : CHICKEN 5 release. ; 1.2.0 : Fix {{*error-print}}.
