Split line using delimiter

[groorj]

Hello All,

I have been struggling with this problem for some time now. I've browsed the formum history but didn't find a match for what I'm trying to do.

I have a big text file in a linux env and I want to read line by line (this is not a problem) and split the readed line into fields. In perl or php it would be easy to do this but as I am a "newbie" C programmer, I'm having some problems.

So for example the line is:

2004/12/03 12:01:59;information1;information2;information3

I want to get this line and put this info to vars like:
date , var1 , var2 , var3
so I can use this info latter in the program.

Can anyone help me with this ?

Thanks alot,
Gus

Look into the strtok() function.

sscanf() might be a better solution if you need to convert to different data types instead of leaving it in character format.

Also consider sscanf. [edit]So says the pokey writer sounding like an echo.[/edit]

#include <stdio.h>
#include <stdlib.h>

int main(void)
{
   const char line[] = "2004/12/03 12:01:59;information1;information2;information3";
   const char *ptr = line;
   char field [ 32 ];
   int n;
   while ( sscanf(ptr, "%31[^;]%*c%n", field, &n) == 1 )
   {
      ptr += n;
      printf("field = \"%s\"\n", field);
   }
   return 0;
}

/* my output
field = "2004/12/03 12:01:59"
field = "information1"
field = "information2"
field = "information3"
*/
