— procedure: make-condition condition-type continuation restarts field-plist

Create a new condition object as an instance of condition-type, associated with continuation. The continuation is provided for inspection purposes only, not for restarting the computation. The restarts argument is described in Restarts. The field-plist is an alternating list of field names and values for those fields, where the field names are those that would be returned by (condition-type/field-names condition-type). It is used to provide values for fields in the condition object; fields with no value specified are set to #f. Once a condition object has been created there is no way to alter the values of these fields.

— procedure: access-condition condition field-name

Returns the value stored in the field field-name within condition. Field-name must be one of the names returned by (condition-type/field-names (condition/type condition)). access-condition looks up the field-name at runtime, so it is more efficient to use condition-accessor to create an access function if the same field is to be extracted from several instances of the same condition type.

— procedure: condition/report-string condition

Returns a string containing a report of the condition. This is generated by calling write-condition-report on condition and a string output port, and returning the output collected by the port as a string.
