	Calling convention - Wikipedia, the free encyclopedia
		Calling conventions differ in the order passed parameters are placed on the stack, methods for sending data to a function, receiving return data from a function, and methods of Name mangling.
		The cdecl calling convention is usually the default calling convention for x86 C compilers, although many compilers provide options to automatically change the calling conventions used.
		The Pascal calling convention is the reverse of the C calling convention.

		Calling convention numbers should be stable to a particular code generator (e.g.
		If the call is not a varargs call, passing arguments in pascal order (the opposite of cdecl) allows for efficient (and trivial) tail call implementations.
		Because calls to the function happen infrequently, the performance of the call is not very important, but the register reloads avoided in the caller can save a lot of space.

	Using Win32 calling conventions
		Traditionally, C function calls are made with the caller pushing some parameters onto the stack, calling the function, and then popping the stack to clean up those pushed arguments.
		convention that uses registers, but we don't believe it's really that useful in the general case — the save and restore of the registers often removes any speed benefit of using the register for arg passing.
		They have chosen to resolve this by encoding the calling convention into the low-level function names with extra characters (which are often called "decorations"), and these are treated as unrelated names by the linker.

	Conformance Rules
		Convention, Import, or Export may be used to override the default calling convention (see B.1)].
		The default calling convention is protected for a protected subprogram, and for an access-to-subprogram type with the reserved word protected in its definition.
		However, the calling convention of the declaration and body of a subprogram or entry are always the same by definition.

	Hoar: Constitutional Conventions: Chapter 5
		Most of the constitutions which contain provisions for the calling of conventions now provide that they be called after the legislature has submitted the question of a convention to the people and has obtained their approval, such a popular vote to be taken whenever the legislatures themselves may think proper.
		Thus, regardless of whether the legislature may all by itself legally call a convention, it is clear that the weight of authority is against the view that the calling of a convention is among the regular legislative powers.
		Where the call for the convention is not submitted to the people for an expression of their consent, such power as the convention may possess is apparently delegated to it by the legislature on its own authority.

	The Old New Thing : The history of calling conventions, part 1 (Site not responding. Last check: 2007-11-03)
		In the 16-bit world, part of the calling convention was fixed by the instruction set: The BP register defaults to the SS selector, whereas the other registers default to the DS selector.
		The classic (pre-prototype) C language allowed you to call functions without telling the compiler what parameters the function requested, and it was common practice to pass the wrong number of parameters to a function if you "knew" that the called function wouldn't mind.
		To add insult to injury, the called function often spilled the register into memory because it needed to spare the register for something else, which in the "significant computation between the first two parameters" case means that you get a double-spill.

	Adjusting Calling Conventions in Mixed-Language Programming Overview
		In a single-language program, calling conventions are nearly always correct, because there is one default for all routines and because header files or Fortran module files with interface blocks enforce consistency between the caller and the called routine.
		The caller routine uses a calling convention to determine the order in which to pass arguments to another routine; the called routine uses a calling convention to determine the order in which to receive the arguments passed to it.
		The caller routine and the called routine use a calling convention to determine which of them is responsible for adjusting the stack in order to remove arguments when the execution of the called routine is complete.

		They have their own calling convention for invocation from a VOP, but implement various block-move operations on the stack contents followed by a return or tail-call operation.
		The main difference between the full call and local call protocols here is that local calls use a different frame setup protocol, and will tend to not use the normal frame layout for the old frame-pointer and return-address.
		Again, in the old convention this was a two-byte unconditionl jump, and in the new convention this is a conditional jump based on the carry flag.

	Calling Convention (Site not responding. Last check: 2007-11-03)
		A calling convention is an agreement about how subroutines are called and how control is returned to the caller.
		This is largely because the calling conventions are different.
		These chapters discuss several calling conventions that show what calling conventions are about, but are not the calling convention of any particular operating system.

	Calling conventions (Site not responding. Last check: 2007-11-03)
		The calling convention determines how a program makes a call and where the parameters are passed.
		In a single-language program, calling conventions are nearly always correct, because there is one default for all modules, and because the compiler and explicit interfaces enforce consistency between the caller and the called routine.
		This convention differs from that used in languages such as C. In C, parameters are pushed onto the stack in reverse order, and the calling program is responsible for restoring the stack.

	Using Win32 Calling Conventions
		The default calling convention is __cdecl, but each one can be requested explicitly with the /G? parameter to the compiler.
		Before one lambasts the programmer for making such a foolish mistake, consider that the default calling convention is usually __cdecl, so even if the file1.c example omitted the declaration for foo(), it would still default upon first use to __cdecl.
		In most cases, it makes no difference either which calling convention is used by default throughout the program, or what the convention is on any particular function, but there are a few exceptions of note when using other than __cdecl for the default.

	DPLOTLIB Interface Routines for DPlot - Calling Convention (Site not responding. Last check: 2007-11-03)
		The primary difference between __cdecl and __stdcall is that with __cdecl functions it is the caller rather than the called function that removes arguments from the stack.
		It may be necessary for you to use this DLL if, for example, your program calls __cdecl functions in another library or object module and it is not possible with your compiler to use both __cdecl and __stdcall.
		This might very well happen with, for example, the g77 FORTRAN compiler, since the calling convention used for all object modules is specified with a single commandline switch rather than with interface definitions for specific functions.

	Zephyr Calling Convention Language (CCL)
		Procedure calling conventions are used to provide uniform procedure-call interfaces.

	How To Call C Functions That Use the _cdecl Calling Convention
		It is not possible to directly call a C function in a DLL if that function uses the _cdecl calling convention.
		This is because Visual Basic uses the _stdcall calling convention for calling functions.
		If it is necessary to call functions that use the _cdecl calling convention (such as the MSTEST DLLs), wrap the _cdecl call inside a _stdcall call that is exposed or exported to Visual Basic.

		Four styles of calling conventions are supported using the PGI Fortran compilers for NT: Default, C, STDCALL, and UNIX.
		This convention will be used if no directives are inserted to modify calling conventions and if the -Munix compilation flag is not used.
		Using the C calling convention requires the insertion of a compiler directive into the declarations section of any Fortran program unit which calls the C program unit.

	Calling convention for FinalizerPtr (Site not responding. Last check: 2007-11-03)
		FinalizerPtr is defined as: type FinalizerPtr a = FunPtr (Ptr a -> IO ()) However, there is no way to specify what the calling convention for a FunPtr is. The calling convention is specified by the foreign import declaration when calling one: foreign import ccall "dynamic" foo...
		In the case of finalizers, the ForeignPtr implementation must pick a calling convention to call the finalizer with.
		This means that you can only use finalizers which expect the ccall calling convention, something that isn't specified in the FFI addendum, or the documentation for newForeignPtr.

	The Old New Thing : What can go wrong when you mismatch the calling convention?
		Someone misdeclares the calling convention, and you detect this and silently fix their error instead of loudly killing the offending application and asking the user to type in the name of the application and the address of its author, so that it could be posted on the Internet in the Official List of Misbehaving Programs.
		You MUST (without exception) declare the calling convention that your library was compiled with in the published headers for the library.
		The problem was that they didn't specify a calling convention in their makefiles, which meant that they assumed that our functions were declared with the default calling convention, __cdecl.

	XL2000: "Bad DLL Calling Convention" When Running a Macro
		Functions that use the _cdecl calling convention are not supported.
		Most 32-bit DLLs that are included with Microsoft Windows support the _stdcall calling convention; the _cdecl calling convention is generally used by older DLLs.
		This behavior occurs because macros in Microsoft Excel 2000 cannot call functions that use the _cdecl calling convention.
