file offset

Each open file has a "current file offset" associated with it. It is usually a non-negative integer that measures the number of bytes computed from the beginning of the file. Typically, read and write operations start at the current file offset and

The relationship between file descriptors and open files in Linux Guide The kernel (kernel) accesses files using file descriptors (descriptor). The file descriptor is a non-negative integer. When you open an existing file or

First, the IOCTL functionThe IOCTL is used to control and configure commands to the device, and some commands also need to read and write some data, but the data cannot be read and written by Read/write, known as out-of-band data. That is,

1. Fork1.1 The parent-child process created by Fork for the FD that was opened before fork, the shared file offset. this is because, after the parent process has forked a child process, it has its own process table entry, so they have a set of

by literal meaning, unistd.h is a UNIX-defined UNIX-class system-defined symbolic constant header file, which is meant by unix-based std. Contains function prototypes for many UNIX system services, such as the Read function, the Write function, and

In the C program, the file is represented by a file pointer or a file descriptor. ISO C's Standard i/0 library functions (fopen, Fclose, Fread, Fwrite, fscanf, fprintf, etc.) use file pointers, Unix I/O functions (open, close, read, write, IOCTL)

When multiple control threads share the same memory, you need to ensure that each thread sees a consistent view of the data.If the variables used by each thread are not read and modified by other threads, then there is no problem of consistency.The

Recently, I have practiced shelling. I will use the 98 notepad with Armadillo 3.10 shelling for the test. 52 K --> the file size reaches 588 K after the 324K shelling, which is more than 10 times the size before shelling, so I want to lose weight,
