SUMMARY
=======

The example below shows how to use the sscanf() C run-time function to read from
an internal buffer delimiting fields with a comma (,). The key is to use the
brackets in the format of sscanf() function. The format will be %[^','], which
tells the function to read from the buffer until a comma (,) is reached.

Sample Code
-----------

  /* The following sample illustrates the use of brackets and the
     caret (^) with sscanf().
     Compile options needed: none
  */ 

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

  char *tokenstring = "first,25.5,second,15";
  int result, i;
  double fp;
  char o[10], f[10], s[10], t[10];

  void main()
  {
     result = sscanf(tokenstring, "%[^','],%[^','],%[^','],%s", o, s, t, f);
     fp = atof(s);
     i  = atoi(f);
     printf("%s\n %lf\n %s\n %d\n", o, fp, t, i);
  }
