how to implement a function table

dragondad · 09-16-2005, 10:12 AM

I have a project, which need to implement a function table for multiple thread call, each thread will start with a different function, and the function table should be a good solution, but I can not find the good reference or programming guide for it.
Please help me out, either a sample (working sample) or an URL.
Thanks.

I'm not sure what a function table is. You mean an array of function pointers or something else?

You are right, it is an array or structure of function pointer.

Code:

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

int fee ()
{
  return printf ("fee!\n");
}

int fi ()
{
  return printf ("fi!\n");
}

int fo ()
{
  return printf ("fo!\n");
}

typedef int (*pMyfn)();
pMyfn myfns[] = 
{
  fee,
  fo,
  fi
};

/*
 * sample output:
 *  fee!
 *  fo!
 *  fi!
 */
int
main(int argc, char *argv[])
{
  int i;

  for (i=0; i<3; i++)
    (myfns[i])();

  return 0;
}
