Macro Definition Documentation

XCB_WRAPPER

#define XCB_WRAPPER	(		__NAME__,
			__REQUEST__,
			... )

Value:

    XCB_WRAPPER_DATA(__NAME__##Data, __REQUEST__, __VA_ARGS__) \
    typedef Wrapper<__NAME__##Data, __VA_ARGS__> __NAME__;

Macro to create Wrapper typedef and WrapperData.

This macro expands the XCB_WRAPPER_DATA macro and creates an additional typedef for Wrapper with name __NAME__. The created WrapperData is also derived from __NAME__ with "Data" as suffix.

Parameters

__NAME__	The name for the Wrapper typedef
__REQUEST__	The name of the xcb request, passed to XCB_WRAPPER_DATA
__VA_ARGS__	The variadic template arguments for Wrapper and WrapperData

XCB_WRAPPER_DATA

#define XCB_WRAPPER_DATA	(		__NAME__,
			__REQUEST__,
			... )

Value:

    struct __NAME__ : public WrapperData<__REQUEST__##_reply_t, __REQUEST__##_cookie_t, __VA_ARGS__> \
    {                                                                                                \
        static constexpr request_func requestFunc = &__REQUEST__##_unchecked;                        \
        static constexpr reply_func replyFunc = &__REQUEST__##_reply;                                \
    };

Macro to create the WrapperData subclass.

Creates a struct with name __NAME__ for the xcb request identified by __REQUEST__. The variadic arguments are used to pass as template arguments to the WrapperData.

The __REQUEST__ is the common prefix of the cookie type, reply type, request function and reply function. E.g. "xcb_get_geometry" is used to create:

• cookie type xcb_get_geometry_cookie_t
• reply type xcb_get_geometry_reply_t
• request function pointer xcb_get_geometry_unchecked
• reply function pointer xcb_get_geometry_reply

Parameters

__NAME__	The name of the WrapperData subclass
__REQUEST__	The name of the xcb request, e.g. xcb_get_geometry
__VA_ARGS__	The variadic template arguments, e.g. xcb_drawable_t
