Dear All

I am trying to align the typecasting (FORMATTING) using C/C++-> Code Style-> Formatter-> Whitespace

But I want the formatting of the typecast in the following stye:

(*(uint64_t *const) someVariable);

The Problem is Eclipse 4.14 format the typecast in the way shown below:

(*(uint64_t* const ) someVariable);

I want the pointer to be attached to const NOT uint64_t and also I donot want the spacing after const as shown above. HELP ME in this regard.

Many Thanks

I am not an expert in C/C++ but will try to give an answer or at least a point for discussion.

A pointer is a pointer to a variable, in this case a variable of type uint64_t. The compiler/linker will know where the variable is located and generate the physical address as value of the pointer.
When you define the variable as const then this is a special feature of this variable, and the compiler will generate an error (maybe a warning) if anywhere in the program the value of this variable shall be changed.
Anyway with or without const the pointer always will point to the adress of the variable. The pointer cannot point to the feature const.

For the compiler it is irrelevant if there is a spacing or not. With spacing is the common way to type.

@Nick Schweyer

Hi Nick, I completely agree with You but I just to format typecasting using predefined standards that's why I am asking that whether in Eclipse we have some setting to introduce space or asterisk (*) alignment by our own choice. I have sen in eclipse CDT C/C++ under C/C++-> Formatter-> WhiteSpace-> .. There are some option with respect to spacing but no options with regard to asterisk alignment specifically under Type casts option.
