[02/03] Avoid calling a shared function at the same time.

Hi,

I have a shared function which can only be called once if it is called at the same time in a program, it would produce error. How can avoid this?

thanks

A crude solution would be to use a global boolean variable set to false. The function first checks if it is still false then runs and sets it to true. After that it won't execute again.

Edit: I read your question more carefully, set it to true while the functions executes and at the end set it back to false.

How about using a SyncLock object?
