The offset variable is declared at function scope but used within a local block scope. This could lead to incorrect behavior as offset is initialized to 0 at the top of the function but then reused for a different purpose in the read operation later.

The variable offset is being reused for both write and read operations. Consider using separate variables (e.g., writeOffset and readOffset) to improve code clarity and prevent potential bugs.
