connect( clientfd, (structsockaddr *)&server_addr,sizeof(server_addr)) ) 上面红色的 htons 函数的作用是将 端口号 由主机字节序转成网络字节序,网络字节序大多时候都是固定为大端字节序的,但不同的机器,主机字节序却不一样,如果本身就已经是大端了,调用 htons 函数,返回值和实参是一样的,如果本身是小端...
Alternatively, the first character of the format string can be used to indicate the byte order, size and alignment of the packed data, according to the following table: If the first character is not one of these,'@'is assumed. Native size and alignment are determined using the C compiler’...

To represent a greater integer, a processor must use a concatenation of bytes, known as a word. Using a single instruction, many processors can read or write a word greater than a byte, although the size of that word in bytes must usually be power of 2. Typical sizes for access are 2...
