Self-Assignment in ANSI C

ansi-c, c, embedded, iar

Solution

Without further information, one use of such a statement is to prevent an unused parameter compiler warning if `rxStruct` is passed in as a parameter and then otherwise not used.

Problem

I am currently working on a embedded C project and I "inherited" some old code containing statements such as: ``` rxStruct = rxStruct; ``` where rxStruct is a variable. What could be the use of such statements?
