It was thus said that the Great Philip Pemberton once stated: I write some C code (included below---it's quite short) to decode the Cuecat datastream (tested and works, at least under Linux). I got the thing (free from RatShack), played around with it for oh, a day or so (that's when I wrote the software) and then never did anything with the thing afterwards. -spc (oh wait ... hold old is the cuecat now?) #include <stdio.h> #include <stdlib.h> #include <string.h> #include <assert.h> #include <ctype.h> /*******************************************************************/ char *cuecat_convert(char *dest,size_t size,const char *src) { int t[4]; unsigned long value; char *sdest; int i; char *p; static const char *const convtable = "abcdefghijklmnopqrstuvwxyz" "ABCDEFGHIJKLMNOPQRSTUVWXYZ" "0123456789+-"; /*"0123456789,/";*/ assert(dest != NULL); assert(size > 0); assert(src != NULL); sdest = dest; while((size > 3) && (*src != '.') && (*src != '\0')) /* oops */ { memset(t,0,sizeof(t)); for (i = 0 ; (*src != '.') && (i < 4) ; i++ , src++) { p = strchr(convtable,*src); if (p == NULL) break; t[i] = p - convtable; assert(t[i] >= 0); assert(t[i] <= 63); } value = (t[0] << 18) | (t[1] << 12) | (t[2] << 6) | (t[3]); value ^= 0x00434343ul; dest[0] = (value >> 16) & 0x000000FFul; dest[1] = (value >> 8) & 0x000000FFul; dest[2] = (value) & 0x000000FFul; dest[3] = '\0'; dest += 3; size -= 3; } *dest = '\0'; return(sdest); } /***************************************************************/ char *cleanup(char *src) { char *ssrc = src; assert(src != NULL); for ( ; *src ; src++) { if ((*src < 32) || (*src > 126)) *src = '.'; } return(ssrc); } /***************************************************************/ int main(int argc,char *argv[]) { char *id; char *type; char *code; char buffer[BUFSIZ]; char cid [BUFSIZ]; char ctype [BUFSIZ]; char ccode [BUFSIZ]; while(fgets(buffer,BUFSIZ,stdin)) { id = strchr(buffer,'.'); if (id == NULL) continue; else id++; type = strchr(id, '.'); if (type == NULL) continue; else type++; code = strchr(type, '.'); if (code == NULL) continue; else code++; cleanup(cuecat_convert(cid,BUFSIZ,id)); cleanup(cuecat_convert(ctype,BUFSIZ,type)); cleanup(cuecat_convert(ccode,BUFSIZ,code)); printf("ID: %s TYPE: %s CODE: %s\n",cid,ctype,ccode); } return(0); } /*******************************************************************/
