JSString * JS_DecompileFunctionBody(JSContext *cx,
    JSFunction *fun, uintN indent);

Name	Type	Description
cx	JSContext *	The context in which to decompile the function. Requires request. (In a JS_THREADSAFE build, the caller must be in a request on this JSContext.)
fun	JSFunction *	The function to decompile.
indent	uintN	The number of spaces to use for indented code.

[edit] Description

JS_DecompileFunctionBody generates the source code of a function's body, minus the function keyword, name, parameters, and braces, from a function's compiled form, fun.

If successful, JS_DecompileFunctionBody returns a string containing the source code of the function body. Otherwise, it returns NULL.

The source code generated by this function is accurate but unadorned and is not suitable for recompilation without providing the function's declaration. If you decompile a function that makes a native C call, the body of the function only contains the text "[native code]".

[edit] Notes

To decompile a complete function, including its body and declaration, call JS_DecompileFunction instead.
