[Process-Thread] HW3 DL : 0: c语言，多线程实现简单的终端处理器，读取文件，遇到特殊字符时采取相应操作 -A multi-threaded program using the pthread library. Your assignment is to write a program that emulates a simple terminal handler. The terminal handler process consists of three threads. Thread 1reads characters from input. In the input, some upper case letters represent control characters. Each character read by thread 1 is passed onto thread 2 before another is read. Thread 2 stores the characters as received. However, the following four characters are control characters that ask thread 2 to take action accordingly. B – erase last character from buffer L – insert an end-of-line marker into buffer C – remove contents of buffer U – remove current incomplete line from buffer The third thread, Thread 3, should read complete lines of characters (a line of character is complete, if it has an end-of-line character) from the buffer. Thread 3 should then print this line. Thread 2 should allow access only to completed lines in the buffer. You may assume that a completed line

[Process-Thread] producer-and-consumer DL : 0: 创建4个POSIX线程。其中2个线程(A和B)分别从2个数据文件(data1.txt和data2.txt)读取10个整数. 线程A和B把从文件中读取的逐一整数放入一个缓冲池. 缓冲池由n个缓冲区构成（n=5，并可以方便地调整为其他值），每个缓冲区可以存放一个整数。另外2个线程，C和D，各从缓冲池读取10数据。线程C、D每读出2个数据，分别求出它们的和或乘积，并打印输出。-Creating four POSIX threads. Where two threads (A and B) were read 10 integer from 2 data files (data1.txt and data2.txt). Individually integer thread A and B to read from a file into a buffer pool. Cushion buffer pool constituted by n (n = 5, and can be easily adjusted to other values), each buffer can store an integer. Further two threads, C and D, the data is read from the buffer pool 10. Thread C, D 2 data is read out of each, and are obtained separately, or product thereof, and print output.
