At the same time, tape devices can be opened, written, and closed by a variety of programs. You can store several backups (tape files) onto a physical tape. There is a "tape file mark" between each tape file. This is used to indicate the end of a tape file on a physical tape and the beginning of another file. You need to use
indicate the end of a tape file on a physical tape and the beginning of another file. You need to use the MT command to locate the tape (fast forward, rewind, and Mark).How the data on the tape is storedAll data is stored continuously in a continuous tape storage format using TAR. The first tape archive begins storage (tar #0) from the physical start of the tape. The next step is the tar #1, and so on.Tape Device name on Unix/dev/rmt/0 or/DEV/RMT/1 o

PHP advanced application for PHP file processing allows you to locate and query file pointers, so as to quickly query required information. file pointer functions include rewind (), fseek (), feof () and ftell () functions. In the previous article "advanced application for PHP file processing-remote file access and file locking", we introduced the remote access to files and how to lock files, let's take a look. I will not talk about it much here. toda

Another scenario is that the class definition is hidden, or the class definition cannot be used to generate a subclass.Instance

While (ch! = EOF)

In this example, a string must be added at the end of the string file. Therefore, the string file is opened in the append-read-write mode in line 2 of the program. Enter a string and use the fputs function to w
