Reader-writer problem (Readers-writers problem) is also a classic concurrent programming problem, which is often a synchronization problem. Data (Files, records) in a computer system are often shared by multiple processes, but some of these processes may require only read data (called Reader readers), while others require the modification of data (called writer writers). In terms of shared data, reader and

scheduling class that does not allow preemption.reader Writer's questionProblem description A data object can be shared by multiple concurrent processes. Some of these processes may only need to read the contents of the shared object, while other processes may want to update the contents of the shared object. Reader: Only interested in the process of reading; written by: Other processes (write only, or read and write); Rules allows multiple readers to read data at the same time; There i

Internship environment: Windows XP + VC 6.0 Internship objectives: Create a console process in Windows XP, which should contain n threads. Use the n threads to represent n readers or writers. Each thread performs read/write operations according to the requirements of the corresponding test data file (described later. The semaphore mechanism is used to implement reader-first and writer-first issues respectively. Restrictions on reader-

In the program, a character equals two bytes, and a Chinese character occupies two bytes (General Limited interview will ask: A char can save a Chinese character, the answer is, of course, a char and a Chinese character accounted for two bytes), the general use of byte stream if defined as odd number of length is, then stored Chinese characters will hav

Recently made some study notes in the blog park. One is the official Swift book from Apple, and the other is learning scheme with the school classroom (SICP).Neither of these languages is widely spoken (or swift newness). The original Windows Live Writer code highlighting plugin in the blog Park does not apply to these languages.So I had to find my own way. First I found the highlight.js this JS highlight plugin. Search to its official website. Follow

1.Reader WriterWhen we first saw the Reader and Writer classes, we might think that this was two classes to replace InputStream and Outputstreamt , but that is not the case.Although some of the original "stream" libraries are no longer used (if they are used, you will receive compiler warning messages), InputStream and Outputstreamt can still provide valuable functionality in byte-oriented I/O.
