strtok的用法(文件操作)

char *strtok( char *strToken, const char *strDelimit );

 char *array[32];
 int index = 0;
#if 0
 array[index] = strtok(buf, " ");
 while(array[index] != NULL){
  printf("%s\n", array[index]);
  index ++;
  array[index] = strtok(NULL, " ");
 }
#else
 for(array[index] = strtok(buf, " "); array[index] != NULL; index++,   array[index] = strtok(NULL, " "))
  printf("%s\n", array[index]);
#endif
