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 ...
This is less efficient than declaring a function and calling it within your code, because functions declared with the function statement are parsed with the rest of the code. All arguments passed to the function are treated as the names of the identifiers of the parameters in the function to ...
When other functions with output parameters are called in a function and an assignment expression, set the GUC parameterset behavior_compat_optionsto'proc_outparam_override', define variables of the same type as the output parameters in advance, and use the variables as output parameters to call ...
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...
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: ...
If a resumable exception is propagated with RAISING without the addition RESUMABLE, it becomes non-resumable. If a superclass is declared as resumable, any subclasses must also be declared as resumable.The addition EXCEPTIONS is used to define a list of non-class-based exceptions that can be ...
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. ...

Keyword arguments must agree with declared parameters in number, but they may be specified in arbitrary order. Default parameters allow some arguments to be omitted when the function is called.Mutable Default Parameter ValuesThings can get weird if you specify a default parameter value that is a ...
