用于开发基于MEGA8上的小系统OS，很经典很小。适合于低配置的单片机上面开发使用。(For the development of small systems based on MEGA8 OS, is the classic small. Configure the microcontroller for low use of the above development.)

ree(void *p)函数是用来释放程序动态申请的内存。其参数是个指针类型。在C当中，只有当使用了动态内存申请函数malloc calloc realloc申请内存之后，才可以使用free来释放之。释放之后就不能再使用了。(ree (void* p) function is used to release the program dynamically allocated memory. Its argument is a pointer type. In C, only apply when using the dynamic memory functions malloc calloc realloc application memory before you can use free to release it. After release no longer use.)
