CHARF is a fixed-length character string. You can use this datatype in VAR and TYPE statements to equivalence C datatypes to the fixed-length SQL standard datatype CHAR, regardless of the setting of the DBMS or CHAR_MAP option. When DBMS=V7 or V8, specifying the external datatype CHARACTE...

try Statements and Exceptions A try statement specifies a code block subject to error-handling or cleanup code. The try block must be followed by a catch block, a finally block, or both. The catch block executes when an error occurs in the try block. The finally block executes after execut...

We describe this in Chapter 7, Collections. Multiple yield statements are permitted. For example: Copy class Test { static void Main( ) { foreach (string s in Foo( )) Console.WriteLine(s); // prints "One","Two","Three" } static IEnumerable<string> Foo( ) {yield return "One"; ...
The text to be printed is enclosed in double quotes. The \n at the end of the text tells the programme to print a newline as part of the output. Most C programs are in lower case letters. You will usually find upper case letters used in preprocessor definitions (which will be ...
The project structure (targets, source files, etc) are not duplicated in the.vgdbsettingsfile. Instead, they are queried directly from CMake and rendered in Solution Explorer. Using Solution Explorer to add new files, or change any settings will directly update the necessary statements inCMakeLi...
As you can see, we left some PDEBUG statements in the code. When you compile the driver, you can enable messaging to make it easier to follow the interaction of different processes. Let us look carefully at how scull_p_read handles waiting for data. The while loop tests the buffer with...
The Arduino build system automatically locates libraries referenced by a project by scanning sketch files for#include<>statements. Including a header file published by a library will automatically pull the entire library into the project. The build process will look for Arduino libraries in the follow...
