在stdio.h有一个非常重要的东西,文件指针,每个文件都会在内存中开辟一块空间,用于存放文件的相关信息,这些信息保存在一个结构体中: struct _iobuf { char *_ptr; //指向buffer中第一个未读的字节 int _cnt; //记录剩余的未读字节的个数 char *_base;//文件的缓冲 int _flag;//打开文件的属性 int _...
voidmain(){if((fp=fopen("example.c","r"))==NULL)/* 只读方式打开一个文件 */printf("error");else{cbuffer=fgetc(fp);/* fgetc( )函数:从磁盘文件读取一个字符 */while(cbuffer!=EOF){if(cbuffer==' '||cbuffer=='\n')/* 掠过空格和回车符 */cbuffer=fgetc(fp);else{if(isalpha(cbuf...

static_stream:针对静态数据buffer优化的静态流,用于轻量快速的数据解析。 协程库 快速高效的协程切换支持 提供跨平台支持,核心切换算法参考boost,并且对其进行重写和优化,目前支持架构:x86, x86_64, arm, arm64, mips32 提供channel协程间数据通信支持,基于生产、消费者模型 提供信号量、协程锁支持 socket、stream都...
Thegetlinefunction returns itsistreamargument so that, likethe input operator, it can be used as a condition. For example, wecould rewrite the previous program that wrote one word per line towrite a line at a time instead: getline函数将istream参数作为返回值,和输入操作符一样也把它用作判断条...
