void rle_addhist( argv, in_hdr, out_hdr )
char **argv;
rle_hdr *in_hdr, *out_hdr;
rle_addhist is used to add history
comments to the RLE(5)
file in the form:
HISTORY=cmd arg1 arg2 on Tue Sep 13 01:06:49 WST 1988
where cmd, arg1, etc. are the command line arguments which have been used
to generate or filter this RLE file. The HISTORY comment is always appended
to so that an accumulated history is kept along with a timestamp. Programs
which generate RLE files should call rle_addhist as follows:
rle_addhist(argv,(rle_hdr *)0,&out_hdr);
Programs which filter RLE files should call rle_addhist as:
rle_addhist(argv,&in_hdr,&out_hdr);
