* newheader(t,fp) start new information header identified by string t |
10 |
|
* isheadid(s) returns true if s is a header id line |
11 |
|
* headidval(r,s) copy header identifier value in s to r |
12 |

* dateval(t,s) get capture date value |
13 |

* fputdate(t,fp) put out the given capture date and time |
15 |

* fputnow(fp) put out the current date and time |
16 |
|
* printargs(ac,av,fp) print an argument list to fp, followed by '\n' |
17 |
|
* isformat(s) returns true if s is of the form "FORMAT=*" |
18 |
|
* formatval(r,s) copy the format value in s to r |
24 |
|
* To copy header from input to output, use getheader(fin, fputs, fout) |
