  1. the kernel uses three data structures to indicate opened files. The relationship between them determines the impact of one process on another process in file sharing.   (1) Each process has a record item (task_struct) in the progress table,

We all know that all the devices under Linux are files, so when we need to use them, we need to open them first, and let's look at the file I/O operations in detail below.The file I/O used has the following actions: Opening a file, reading a file,

In a C program, a 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 descriptors, Unix I/O functions (open, close, read, write, IOCTL).

All open files have a current file offset, which is referred to as the CFO. The CFO is typically a non-negative integer that indicates the number of bytes at the beginning of the file to the current location of the file. Read and write operations

The article first introduces the structure of the file content of Qqwry.dat and then according to its characteristics we can write read the contents of the Qqwry.dat IP library to find what we want. First look at the content structure of the

Basic knowledge1. Virtual Address and offset ConversionBecause Windows programs run in 386 protection mode, in protection mode, the logical address used by the program to access the memory is called virtual address (virual address, VA ). Similar to

Many of my friends like to listen to the PE explanation of Tom, because they think that what the teacher explained in the class was omitted, and it was difficult for everyone to go around ~ It's just that little turtle's literary talents are not as

All open files have a current file offset (CFO. CFO is a non-negative integer used to indicate the number of bytes from the beginning of the file to the current position of the file. Read/write operations usually start with CFO, and increase CFO,

A few days ago, I spoke to my friends about the technology and mentioned how to create a micro-PE file. He said that most of the versions circulating on the Internet cannot run under XP SP3, so I came to my heart and said: "You don't have to worry

All the section attributes in the PE file are defined in the section table. The Section Table is arranged by a series of image_section_header structures. Each structure is used to describe a section, the order of the structure is the same as the

Lseek Function Off_t lseek (intFiledes, Off_tOffset, Int whence ); Whence: seek_set, which indicates that the offset of the file is set to the offset byte starting from the file. Seek_cur. Currently, the value is + offset bytes. The offset value can
