非阻塞I/O可以使用fcntl参数进行设置READ/RECVFROM,但很明显它的尝试次数非常多。 [windriver@windriver-machine ltest]$ gcc noread.c -o noread [windriver@windriver-machine ltest]$ strace -e read -o out.txt ./noread aaa aaa bbbbb bbbbb ccccc ccccc [windriver@windriver-machine ltest]$ cat out...

由于C/C++是偏底层的高级语言,因此它们的标准库中牵扯到很多和操作系统相关的接口,例如read/write,内存分配、线程调度等,这些操作都牵扯到系统调用(system call),因此不同的操作系统应该会有不同的标准库的实现? 如图1所示,GCC,MSVC,CLANG是目前最主流的C/C++编译器,编译器是一组程序(这里包含链接等程序),它们...

在 Go 语言中,io.Reader 是几个基本接口之一,它定义了一个阻塞的 Read 方法。因此,当需要从文件描述符或者 TCP 连接中读取数据时,该方法会被阻塞,直到有数据到达或者stream被关闭。相比之下,在 C++ 中编程,我们可以同时从多个stream中读取,直到它们中至少有一个变为可读。
