Linq (a chain-style code sugar ) greatly improve beauty of C#, could make your code designed like: Select.Where.Orderby... As standard C do not offer extend-function. But you could still make the chain like Order(Select(Where(Data))) . Some little bit harder ,but much more easier th...
最后提一点,Objective-C与C++相比,支持子类覆盖超类的方法,而不支持同一个类中重载方法。 参考资料: 1. Write Objective-C Code 2. Learning Objective-C 2.0

A: maybe c code version isn't effective, and test is undulate between +-5000 rps. Q: > The result may be incredible, but it is possible, the magnitude of IO is milliseconds Depends, really. With io_uring, or user-space network stacks, you get IO in the microseconds/nanoseconds range...

write()写文件函数 原形：int write(int handle,char *buf,unsigned len)功能：将缓冲区的数据写入与handle相联的文件或设备中，handle是从creat、open、dup或dup2调用中得到的文件句柄。对于磁盘或磁盘文件，写操作从当前文件指针处开始,对于用O_APPEND选项打开的文件，写数据之前，文件指针指向EOF；对于...
然后再顺带讲解 close 接口和 write 接口,在讲解这些系统底层文件接口前,我们还需要复习一下 C 语言中的文件操作知识,需要重新理解文件操作,不能仅停留在语言层面,而是要将眼光放宽到操作系统的层面去看待!重新理解当前路径、复习文件读取的接口 (fopen, fgets) 和文件操作模式 (w, r, a, a+) 后,再讲解文件...
