How to make a "local global " variable?

Hello,

I would like to share some variables among some functions. It is inconvenience to make them all as arguments, because that makes the command too long. Is there a way to add these variable in a special "global variable pool"? A global variable is defined under all functions, which is not appropriate for me. I only want them to be shared among several functions.

Thank you for any helpful suggestion.

The standard efficient solution is to put them into one structure and pass that.

@Stephen since using a struct is likely to be the best solution by far, I would suggest you move it to the answers section.

Yes. You are right. Thank you for your good solution.

No, that does not exist.

• you can create accessor functions that deal with persistent variables inside a private directory
• you can put the functions togther in a class with class variables
• if all relevant functions can be in the same source file, then you can use nested functions with shared variable
• or pass a struct instead
