- ERRORS
-
- We print the error message 1st, beginning in column 1.
- All ancillary info starts in column 2 on lines after the
- key error text.
- We try to print a location in logical and physical file
- just after the main error text.
- Caller then prints any appendices after that, begining all
- lines with at least 1 space.
-
- Optionally, we may die.
- There is no need for a trailing '\n' in your error text format
- because we supply one.
-
- as_warn(fmt,args) Like fprintf(stderr,fmt,args) but also call errwhere().
-
- as_fatal(fmt,args) Like as_warn() but exit with a fatal status.
