strtok problems

Hello

I am having problems using strtok on string like:
1,,Andrew,Dunn,215,63,,,342,,,,,

each comma delimits a record, so i need the string to tokenise to:
record-1
record-
record-Andrew
record-Dunn
record-215
record-63
record-
record-
record-342.....etc

But strtok seems to ignore the records that are ,,.

Is there an easy way around this?

cheers
in advance

Andy

Are you using C or C++? If C++, I'd suggest boost::tokenizer instead.

in vanilla C:

Code:

---

#include <string.h>
#include <stdio.h>

int main(){
        char working[80];
        char *buf,*end;
        char comma = ',';
        int flds=0;
        strcpy(working,"1,,Andrew,Dunn,215,63,,,342,,,,,");
        for(end=working;*end;end++) if(*end==comma) *end=0x00;
        for(buf=working;buf<end;){
                flds++;
                printf("field: %d:%s\n",flds,buf);
                for(;*buf;buf++);
                buf++;
        }
        return 0;
}

Cheers boys

parksie, thanks i've been looking at the boost tokenise

and thanks jim, your suggestion works as well, just have to see which one i'm allowed to use!

Thanks again

Andy

Jim's will almost certainly be the fastest method, but he's dropped out a large proportion of the error checking from that.

PS: If your teachers or whatever complain about using anything from Boost, point them at the "who's who" and they'll see a surprising correlation with the standards committee :D
