Procedures
Keywords that work with procedures.
Description
These keywords control the declaration and definition of both module-level procedures and member procedures, how they are called, how arguments are passed and how their names are seen externally to other modules. Procedures can also be declared to be executed automatically before any module-level code is executed.
Declaration
Keywords that declare and define procedures.
Linkage
Keywords that specify how procedure names are seen by external modules.
Calling conventions
Keywords that specify how arguments are used when calling procedures.
Parameter passing conventions
Keywords that specify how arguments are passed to procedures.
Variadic Procedures
Macros that allow for an arbitrary number of arguments to be passed to a procedure.
Automatic execution
Keywords that specify automatic execution of procedures.
Miscellaneous
Miscellaneous keywords.

Declaration Declare Declares a module-level or member procedure. Sub Specifies a procedure that does not return an argument. Function Specifies a procedure that returns an argument. Overload Specifies that the procedure name can be used in other procedure declarations. Static Specifies static storage for all variables and objects in the procedure body. Const (Member) Specifies a const member procedure in user-defined type definitions. Static (Member) Specifies a static member procedure in user-defined type definitions. Linkage Public Specifies external linkage for a procedure. Private Specifies internal linkage for a procedure. Alias Specifies an alternate external name for a procedure. Export Specifies a procedure is to be exported from a shared library. Lib Specifies automatic loading of a library. Calling conventions stdcall Specifies the standard calling convention for BASIC languages, including FreeBASIC. cdecl Specifies the standard calling convention in the C and C++ languages. pascal Specifies the standard calling convention in the Fortran, Pascal and Microsoft QuickBASIC/QBasic languages. Fastcall Specifies the fastcall calling convention for 32-bit procedures. Thiscall Specifies the thiscall calling convention for 32-bit member procedures. | Parameter passing conventions ByRef Specifies passing an argument by reference. ByVal Specifies passing an argument by value. Any Disables type-checking on arguments. Variadic Procedures ... (Ellipsis) Indicates a variadic procedure in a declaration. Cva_Arg Macro to obtain the next argument from a variadic argument list object Cva_Copy Macro to copy a variadic argument list object variable Cva_End Macro to end using a variadic argument list object variable Cva_List Variadic argument list object type Cva_Start Macro to initialize variadic argument list object variable va_first Macro to obtain the argument list in a variadic procedure. va_arg Macro to obtain the current argument in a variadic procedure. va_next Macro to move to the next argument in a variadic procedure. Automatic execution Constructor (Module) Indicates a procedure is to be executed before module-level code. Destructor (Module) Indicates a procedure is to be executed after module-level code. Miscellaneous Byref (Function Results) Specifies that a function returns by reference rather than by value. Call Invokes a procedure. Naked Specifies that a function body is not to be given any prolog/epilog code
