IoSlice — Rust API for Unix // Lib.rs
Web7 nov. 2024 · In Unix-like systems, everything is a file, including sockets, so the way to get raw access to a socket would be to convert it to a file descriptor with AsRawFd.From what I understand, Windows distinguishes files and sockets, so there are separate AsRawHandle and AsRawSocket traits for Windows. In both cases the interface is fairly low-level, but … Web描述符 iovec 主要是用于存放两个内容:用来接收所读取数据的用户地址空间缓冲区的地址和缓冲区的大小;描述符 kiocb 用来跟踪 I/O 操作的完成状态。 之后,函数 generic_file_read () 凋用函数 __generic_file_aio_read ()。 该函数检查 iovec 中描述的用户地址空间缓冲区是否可用,接着检查访问模式,若访问模式描述符设置了 O_DIRECT,则执行与直接 I/O … c语言int k 0 while k 0 k k-1

WebHaving a real iterator, and making biovecs immutable, has a number of advantages: Before, iterating over bios was very awkward when you weren’t processing exactly one bvec at a time - for example, bio_copy_data () in block/bio.c, which copies the contents of one bio into another. Because the biovecs wouldn’t necessarily be the same size ... binging with babish food wars
