Conventions used

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

CodeInText: 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: "For example, look at the difference between using an std::array{} or a std::vector{} command."

A block of code is set as follows:

int array[10];

auto r1 = array + 1;
auto r2 = *(array + 1);
auto r3 = array[1];

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

int main()
{
    auto ptr1 = mmap_unique_server<int>(42);
    auto ptr2 = mmap_unique_client<int>();
    std::cout << *ptr1 << '\n';
    std::cout << *ptr2 << '\n';
}

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

> cmake -DCMAKE_BUILD_TYPE=Release ..
> make

Bold: Indicates a new term, an important word, or words that you see on screen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "Select System info from the Administration panel."
