If the exception specification is non-throwing, the type of the function declared is“derived-declarator-type-list noexcept function ofparameter-type-list cv (optional) ref (optional) returning T”. (since C++17)The(until C++17)Otherwise, the(since C++17) type of the ...
Parameters can be declared in the normal fashion using the Edit Function Parameters panel. However, you should first determine the domain of the parameter fields in your user-written program to ensure that they correspond to the paramete...
1)New-style (C89) function definition. This definition both introduces the function itself and serves as a function prototype for any futurefunction call expressions, forcing conversions from argument expressions to the declared parameter types. ...
In a function module in which class-based exceptions are declared with the RAISING addition, the statement CATCH SYSTEM-EXCEPTIONS cannot be used. Instead, the relevant treatable exceptions should be handled in a TRY control structure. The addition EXCEPTIONS is used to define a list of non-...
A function declared with the single keywordvoidin the parameter declaration list takes no arguments, as long as the keywordvoidis the first and only member of the argument declaration list. Arguments of typevoidelsewhere in the list produce errors. For example: ...

When a variable is declared constant, free references to it are to its permanent constant value, and compilers are free to fold that constant into the code they emit. We introduce the concept of global variables; when a variable is global, free references to it are to the value cell of ...
