Expands to a numeric value that describes the maximum function arity supported by the library.
Defaults to 20 if not explicitly defined by the user before inclusion of the first library header.
The following macros do not need to be defined, unless
to configure the library to work with a compiler and/or calling convention
not covered by the auto-detection mechanism in
Expands to a sequence
of ternary tuples
(these data types are defined in the documentation
of the Boost Preprocessor library). Each sequence element describes
one calling convention specifier. The first element in each tuple is the
macro suffix for
the second element is the name of the tag that describes the calling convention
and the third is the name of the specifier. The specifier is allowed to
be an empty string, so the third tuple element is either
Define this macro to extend the set of possible names for custom calling conventions. The macro expands to nothing by default.
The following names are predefined by the library and must not occur in
the definition of
#define BOOST_FT_BUILTIN_CC_NAMES \ (( IMPLICIT , implicit_cc , BOOST_PP_EMPTY ))\ (( CDECL , cdecl_cc , BOOST_PP_IDENTITY(__cdecl ) ))\ (( STDCALL , stdcall_cc , BOOST_PP_IDENTITY(__stdcall ) ))\ (( PASCAL , pascal_cc , BOOST_PP_IDENTITY(pascal ) ))\ (( FASTCALL , fastcall_cc , BOOST_PP_IDENTITY(__fastcall) ))\ (( CLRCALL , clrcall_cc , BOOST_PP_IDENTITY(__clrcall ) ))\ (( THISCALL , thiscall_cc , BOOST_PP_IDENTITY(__thiscall) ))\ (( IMPLICIT_THISCALL , thiscall_cc , BOOST_PP_EMPTY )) // Don't get confused by the last line, here (thiscall can't be specified // explicitly prior to MSVC 8).
The macro expands to a list of restrictions, separated by the
character. Possible items are:
If no such macro is defined for a particular calling convention, it is disabled. Example:
#define BOOST_FT_CC_STDCALL non_variadic|callable_builtin // enables stdcall calling convention for all non-variadic, // callable, builtin types
Defining this macro causes the following macros to be defined, if not defined already:
#define BOOST_FT_CC_CDECL BOOST_FT_COMMON_X86_CCs #define BOOST_FT_CC_STDCALL non_variadic|BOOST_FT_COMMON_X86_CCs #define BOOST_FT_CC_FASTCALL non_variadic|BOOST_FT_COMMON_X86_CCs
This macro allows to change the syntax of callable builtin types. It is useful to handle the compiler specific placement of the calling convention specifier.
The default definition is as follows:
#define BOOST_FT_SYNTAX(result,lparen,cc_spec,type_mod,name,rparen) \ result() lparen() cc_spec() type_mod() name() rparen()
void for compilers that insist on a
parameter for nullary function types, empty by default.
Disables support for cv-qualified function types. Cv-qualified function
types are illegal by the current standard version, but there is a pending
defect report on that issue. It defaults to
the standard changes, setting this macro to
0 may not
The following macros are useful for testing when changing the source code of the library.
Makes the compiler preprocess as much as possible of the library code (rather than loading already-preprocessed header files) if defined.
