This simple tutorial will show you how to get byte count in a file in Linux.Byteis a unit of digital information that most commonly consists of eight bits. File sizes are measured in bytes. How to get byte count in a file in Linux There are various Linux commands that you can use to...
由于程序中是用sendfile系统调用来发送数据,因此不需要读取文件内容并存储在程序的缓冲区内。 接下来是服务器地址: /* clear the memory */ memset(&sa, 0, sizeof(struct sockaddr_in)); /* ini 尽管有一些缺点,”零拷贝”sendfile是一个很有用的特性。我希望读者认为本文提供了足够的信息以开始在程序中使...
How to count lines in the file in Linux We have a text file in the home directory with the name “myfile.txt”, to display the contents of the text file, use the command: $ cat myfile.txt Method 1: Using the wc command The one method to count the number of lines is by using ...

-->f_count的作用是记录对文件对象的引用计数,也即当前有多少个使用CLONE_FILES标志克隆的进程在使用该文件。典型的应用是在POSIX线程中。就像在内核中普通的引用计数模块一样,最后一个进程调用put_files_struct()来释放文件描述符。 -->f_flags当打开文件时指定的标志,对应系统调用open的intflags,比如驱动程序为了...
#include<sys/sendfile.h>ssize_tsenfile(int out_fd,int in_fd,off_t*offset,size_t count); in_fd参数是待读出内容的文件描述符,out_fd参数是待写入内容的文件描述符。offset参数指定从读入文件流的哪个位置开始读,如果为空,则使用读入文件流默认的起始位置。count参数指定文件描述符in_fd和out_fd之间传输...
