33 | ERRORS | |
34 | ||
35 | JF: this is now bogus. We now print more standard error messages | |
36 | that try to look like everyone else's. | |
37 | ||
38 | We print the error message 1st, beginning in column 1. | |
39 | All ancillary info starts in column 2 on lines after the | |
40 | key error text. | |
41 | We try to print a location in logical and physical file | |
42 | just after the main error text. | |
43 | Caller then prints any appendices after that, begining all | |
44 | lines with at least 1 space. | |
45 | ||
46 | Optionally, we may die. | |
47 | There is no need for a trailing '\n' in your error text format | |
48 | because we supply one. | |
49 | ||
50 | as_warn(fmt,args) Like fprintf(stderr,fmt,args) but also call errwhere(). | |
51 | ||
52 | as_fatal(fmt,args) Like as_warn() but exit with a fatal status. | |
