DOS

说明：  包含操作系统全部试验以及实验报告，稍微修改下就可以了(Contains the operating system all the tests and lab reports, a slight modification can be the next)

说明：  本程序为自己在学习操作系统时独立根据书上所述的银行家算法制作而成，包括一个数组输入函数（Sr()），数组输出函数（Pr()）和一个判断函数（test()），并通过指针传递参数，可以自定义进程数目和资源种类数目（源程序限10个以内，可自行更改数组）。 注：本程序是在linux环境下通过gcc编译器编译成功的。若移植到windows环境下可能在汉字显示部分出现乱码。(This procedure for their own independence in learning, when the operating system on the basis of the book described in banker s algorithm produced, including an array of input function (Sr ()), array output function (Pr ()) and a judging function (test () ), and through pointer parameters, the process can customize the number and type of the number of resources (source 10 within limits, can make changes to the array). Note: This procedure is in the linux environment through the gcc compiler to compile successful. If transplanted into windows environment may display garbled characters.)

1）设计一程序，由一个进程创建三个子进程，三个子进程一个是生产者进程，两个是消费者进程。 2）父子进程都使用父进程创建的共享存储区进行通信，由生产者进程将一个数组中的十个数值发送到由5个缓冲区组成的共享内存中。? 3）两个消费者进程轮流接收并输出这十个数值，同时将两个消费者进程读出的数值进行累加求各和。 4）考虑生产者进程生产的速度和消费者进程速度。(1) a program is designed to create three sub processes from one process, three sub processes is the producer process, and the two is the consumer process. 2) the father child process communicates with the shared storage area created by the parent process, and sends ten values in one array to the shared memory composed of 5 buffers by the producer process. L 3) the two consumer processes take turns to receive and output the ten values, and add values to each of the two consumer processes. 4) take into account the production speed of the producer process and the speed of the consumer process.)

说明：  os design 一个操作系统的设计，里面带有说明书！～！～(os design an operating system design, with brochures inside! ~! ~)
