In what cases is it advisable to avoid using inline functions in code?

Using inline functions (embedded functions) in code helps reduce the overhead of function calls and can improve performance. However, there are situations where their use is undesirable:

• Large size of the function: if the function is large, inlining will increase the code size, which can negatively affect caching and the size of the binary.
• Frequent code changes: when an inline function is modified, all its usage points need to be recompiled, complicating maintenance.
• Recursive functions: inline functions are not suitable for recursion, as this can lead to infinite inlining.
• Debugging: inline functions are harder to debug because they do not have a separate address in memory.

Therefore, it is better to use inline functions for small, frequently called functions, and avoid inlining for complex and large ones.
