Conventions used

There are a number of text conventions used throughout this book.

Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: “The execve() system call, after several iterations where it leaves the confines of userspace, will end up in the Linux kernel and create a linux_binprm structure.”

A block of code is set as follows:

#include <iostream>
typedef struct S {
    int a;
} S, const *CSP;
int main() {
    S s1;
    s1.a = 1;
    CSP ps1 = &s1;
    std::cout << ps1->a;
}

Any command-line input or output is written as follows:

$ g++ main.cpp a.cpp b.cpp -o test
$ g++ main.cpp b.cpp a.cpp -o test
