[section Number of Arguments]

This implementation supports member functions with up to eight arguments. This
is not an inherent limitation of the design, but an implementation detail.

[section:stdcall `__stdcall`, `__cdecl`, and `__fastcall` Support]

Some platforms allow several types of member functions that differ by their
calling convention (the rules by which the function is invoked: how are
arguments passed, how is the return value handled, and who cleans up the stack
 - if any.)

For example, Windows API functions and COM interface member functions use a
calling convention known as `__stdcall`. Borland VCL components use
`__fastcall`. UDK, the component model of OpenOffice.org, uses `__cdecl`.

To use `mem_fn` with `__stdcall` member functions, `#define` the macro
`BOOST_MEM_FN_ENABLE_STDCALL` before including `<boost/mem_fn.hpp>`.

To use `mem_fn` with `__fastcall` member functions, `#define` the macro
`BOOST_MEM_FN_ENABLE_FASTCALL` before including `<boost/mem_fn.hpp>`.

To use `mem_fn` with `__cdecl` member functions, `#define` the macro
`BOOST_MEM_FN_ENABLE_CDECL` before including `<boost/mem_fn.hpp>`.

[*It is best to define these macros in the project options, via `-D` on the
command line, or as the first line in the translation unit (.cpp file) where
`mem_fn` is used.] Not following this rule can lead to obscure errors when a
header includes `mem_fn.hpp` before the macro has been defined.

/[Note:/ this is a non-portable extension. It is not part of the interface./]/

/[Note:/ Some compilers provide only minimal support for the `__stdcall` keyword./]/
