23 * 初始化任务堆栈
24 *
25 * 描述 : 这个函数被OSTaskCreate()或OSTaskCreateExt()调用，以便初始化新创建任务的堆栈结构。本函数
26 * 与处理器高度相关。
27 *
28 * 参数 : task 指向任务代码的指针
29 *
30 * pdata 当任务第一次执行时将要传入任务的用户数据结构指针
31 *
32 * ptos 栈顶指针。ptos指针被默认为用户堆栈入口指针。如果OS_STK_GROWTH被置1，那么，
33 * ptos指向用户堆栈的最高有效地址。同样地，如果OS_STK_GROWTH清0，ptos将指向
34 * 用户堆栈的最低有效地址。
35 *
36 * opt 指定可以改变OSTaskStkInit()行为的选项。(见uCOS_II.H for OS_TASK_OPT_???)。
37 *
38 * 返回值 : 我修改了原来的程序，使函数总是返回用户堆栈空间的最低有效地址。这样修改提高了TCB换入换出
C51 COMPILER V7.50 OS_CPU_C 01/12/2005 21:47:41 PAGE 6
39 * 的效率。
40 *
41 * 注意 : 任务堆栈结构:
42 *
43 * ---------- -
44 * 用户栈最高地址---->| | |
