Something like?

---------------------------
strcpy (cmd, "ls");
strcpy (args[0], "ls");
strcpy (args[1], "-l");
// strcpy (args[2], "*.c");
args[3] = NULL;

pattern = "*.c";
  while(dp = readdir(dirp))
 {
     if((fnmatch(pattern, dp->d_name,0)) == 0)
    {

       strcpy (args[2], )dp->d_name);
       // stuff withh forks
       execvp (cmd, args);
       // stuff

    }
}
---------------------------

But in this case there will be several process created by execvp().
Of course, we need the only process created by execvp().
