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: "Create a brand new Unity Project. I will call mine Snap."

A block of code is set as follows:

struct Circle
{
Circle(int x, int y, int radius) : X(x), Y(y), Radius(radius) {}
int X, Y, Radius;
};

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

extern "C" void __declspec(dllexport) __stdcall  Close()
{
_capture.release();
}

Bold: Indicates a new term, an important word, or words that you see onscreen. 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."
