This command decompiles the selected functions or the whole application. It will ask for the name of the output .c file. If there is a selected area in the disassembly view, only the selected functions will be decompiled. Otherwise, the whole application will be decompiled. When the whole application is decompiled, the following rules apply: * the order of decompilation is determined by the decompiler. It will start with the leaf functions and will proceed in the postnumbering order in the call graph. This order makes sure that when we decompile a function, we will have all information about the called functions. Obviously, for recursive functions some information will be still missing. * the library (light blue) functions will not be decompiled. By the way, this is a handy feature to exclude functions from the output. * A decompilation failure will not stop the analysis but the internal errors will. The decompiler generates #error directives for failed functions. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.hex-rays.com/ida-9.3/ida-actions/hx_createcfile.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
