Hello group,

I will appreciate it if sombody could introduce me a CSV library to handle CSV data in C programming.

I'm about to write a code (have a very short time) but need to get it done as soon as possible so any library that would help me could be a useful thing.

Thanks,

Can you give us a sample of your input?

Why don't just the C "strtok()" function, and choose the delimiter as a comma  (',')?

Thanks for your response. Following is what I'm expecting or even worse. In following I need to access to each column but I only will extract three of them like group, id and domain list.

Any idea?

Thanks.

Is for MacOSX so should be easy to use on *nix

You can also write your own functions with ease
e.g.


char * get_nth_col (char * input, int col)

{

     int n = 0; char * ret = NULL; char * res = NULL; //add check for col<=0 & input == NULL

     char * temp = strdup(input);

     char * token = strtok (temp, ",");

     while (token)

     {

           n++;

           if (n==col)

           {

                 ret = token;

                 break;

           }

            token = strtok(NULL, ",");

     }

      if (ret)

            res = strdup(ret);

      free(temp);

      return res; //note this memory needs to be freed in the calling function

}

Thanks to all for your help. Also, I ran into a good library on sourceforge website called "libcsv".

Regards.
