消息是通过objc_msgSend()这个runtime方法来实现的。这个方法需要一个target,selector,还有一些参数。理论上来说,编译器只是把消息分发变成objc_msgSend来执行。比如下面这两行代码是等价的。 [array insertObject:foo atIndex:5]; objc_msgSend(array, @selector(insertObject:atIndex:), foo, 5); ...

sendfile(int out_fd, int in_fd, off_t*offset", size_t"" count"); The in_fd, out_fd, off_t * offset and the size_t count arguments are required for the function to work. The complete details of these arguments are as follows: ...
Next, we define the value of a variable option to be 1. Utilizing the size_of function, which is equal to address, define the address length variable. Set the size of the character-type array variable buffer to 1024, and define the values to 0. A character-type variable message is then...
