That came up with [url=http://oss.sgi.com/cgi-bin/cvsweb.cgi/linux-2.6-xfs/lib/reed_solomon/reed_solomon.c?annotate=1.1]this link[/url] that has some useful information. It also references "Phill Karn" So I did an advanced search for [url=http://www.altavista.com/web/results?itag=ody&pg=aq&aqmode=s&aqa=%22Phil+Karn%22+%22Reed-Solomon%22&aqp=&aqo=&aqn=&aqb=&kgs=1&kls=0&dt=tmperiod&d2=0&dfr%5Bd%5D=1&dfr%5Bm%5D=1&dfr%5By%5D=1980&dto%5Bd%5D=22&dto%5Bm%5D=11&dto%5By%5D=2006&filetype=&rc=dmn&swd=&lh=&nbq=10]"Phil Karn" "Reed-Solomon"[/url] which yielded the following: [url=http://www.ka9q.net/code/fec/]Forward Error Correcting Codes[/url] - This page references several source files that might be helpful. [url=http://www.ka9q.net/code/fec/]Reed-Solomon coding and decoding by Phil Karn[/url] [url=http://www.piclist.com/techref/method/error/rs-gp-pk-uoh-199609/index.htm]Reed-Solomon coding/decoding package v-1.0[/url] [url=http://oss.sgi.com/cgi-bin/cvsweb.cgi/linux-2.6-xfs/lib/reed_solomon/reed_solomon.c?annotate=1.2]reed_solomon.c[/url] I noticed that the function signatures on these pages look like the ones that you have given. I assume that means that the library you are using was derived from one of these source files so it may be possible to figure out what you need to run the prgram from there. One of the things I noticed on the first [url=http://oss.sgi.com/cgi-bin/cvsweb.cgi/linux-2.6-xfs/lib/reed_solomon/reed_solomon.c?annotate=1.1]link[/url] above is a test of the argument values for the init function [code] ! 195: if (symsize < 1) ! 196: return NULL; ! 197: if (fcr < 0 \|\| fcr >= (1<<symsize)) ! 198: return NULL; ! 199: if (prim <= 0 \|\| prim >= (1<<symsize)) ! 200: return NULL; ! 201: if (nroots < 0 \|\| nroots >= (1<<symsize) \|\| nroots > 8) ! 202: return NULL; ! 203: [/code] This gives a clue as to the values you should be supplying for the parameters to te init function. Unfortunately, it then calls a function "down(&rslistlock)" which is not shown on that page so it's hard to tell what the exact values should be. However, I think there is enough information in the other pages to start to figure it out. . -- not necessarily stoned... just beautiful.
