| 13 | – | *  isheadid(s)         returns true if s is a header id line | 
| 10 |  | *  headidval(r,s)      copy header identifier value in s to r | 
| 11 | + | *  dateval(t,s)        get capture date value as UTC | 
| 12 | + | *  gmtval(t,s)         get GMT as UTC | 
| 13 | + | *  fputdate(t,fp)      put out the given UTC | 
| 14 | + | *  fputnow(fp)         put out the current date and time | 
| 15 |  | *  printargs(ac,av,fp) print an argument list to fp, followed by '\n' | 
| 16 | – | *  isformat(s)         returns true if s is of the form "FORMAT=*" | 
| 16 |  | *  formatval(r,s)      copy the format value in s to r | 
| 17 |  | *  fputformat(s,fp)    write "FORMAT=%s" to fp | 
| 18 |  | *  getheader(fp,f,p)   read header from fp, calling f(s,p) on each line | 
| 22 |  | *  To copy header from input to output, use getheader(fin, fputs, fout) |
