Decompile a function

A decompiler plugin is optional here. You reconstruct the C yourself from what the engine gives you.

1. Call current_view (eleven) for the function in focus, unless the user named one.
2. Read procedure_pseudo_code. If it is missing, or it is really just disassembly (some engines, like Rizin without a decompiler plugin, only disassemble), read procedure_assembly and reconstruct the logic from the instructions.
3. Read procedure_callers and procedure_callees, and any strings the function references, to work out the parameters, the return value, and what it is for.

Then write it out:

• Clean C for the function: real parameter and local names, a struct or enum where the code clearly implies one, and the control flow a person would actually write. Stay faithful to the instructions, do not invent behavior.
• Put a /* ? */ comment on anything you are unsure of.
• rename_function (eleven) it and any FUN_ callees you now understand, and add_note one sentence on what it does.

Answer with the C in a code block, then two or three lines on what it does and anything surprising (error paths, magic numbers, side effects). This is reconstruction from the binary, not the original source; say which parts are a guess.
