Help needed to define and handle custom pragma #mypragma
I want to allow compilation of my own pragma in C/Cpp files such as #pragma mypragma and I want to handle it in this way -- upon identification of this pragma, I want to insert a function call and delete some code in the original source file.
My problem is defining pragma and to handle it for inserting a function call. It would be great if someone can guide or suggest some tutorials. I am referring following resources but being newbie in front-end parsing, it is little hard. So, any help is highly appreciated. Thank you! :)
