第六章:使用 CMake 进行链接 你可能会认为,在我们成功将源代码编译成二进制文件之后,作为构建工程师我们的工作就完成了。事实几乎如此——二进制文件包含了 CPU 执行的所有代码,但代码分散在多个文件中,方式非常复杂。链接是一个简化事物并使机器代码整洁、易于消费的过程。 快速查看命令列表会让你知道 CMake 并没...
Pass an empty array [] as the argument. Use the libpointer function: p = libpointer; % no arguments p = libpointer('string') % string argument p = libpointer('cstring') % pointer to a string argument Use the libstruct function: p = libstruct('structtype'); % structure type Empty...
Name is the function argument or parameter name as defined in your C functions from source code. This column is for reference purposes only. Scope Specifies how C function arguments map to the Simulink scope. Your arguments have default scopes depending on the function definition, and you can...

The logical extension of the concept ofpassing a pointer to a functionleads to passing aUnionpointer, i.e., the pointer of amulti-dimensional array, passing the pointer of aself-referential structure, etc., all these have important uses in different application areas such as complex data struct...
Use the object reference to store the reference to a function, then pass it as an argument to the target function for callback. In the C/C++ DLL, it should include the callback functions a function to return these callback functions (for variables in TS to store them for later use)...
