Do any of you guys know if it's possible to update a text file(e.g something.txt) in C? I was expecting to find a function with similar syntax as update_txt(something.txt), but I haven't found anything while browsing the internet for the last 2 hours..... The thing is that I would like some data to be stored and displayed in real time in an already opened text file. I can store the data but I am unable to find a way to display it without manually closing the text file and then open it again...
Do someone know how to solve this issue? Or do you have another way to solve it? I have read something about transferring data to a new text document and then renaming it, but I am quite sure that this wouldn't solve my problem. I have also read something about macros that could detect changes in the document and then somehow refresh it. I have never worked with macros and I have absolutely no idea of how they are implemented....
But please tell me if it is a fact that it is impossible to update an already opened text document?
I am thankful for any suggestions or tutorials that you guys may provide! :)
That's outside the scope of C; it will require some system-specific filesystem monitoring mechanism. For example, inotify offers this functionality
