Description
JS_DecompileFunction
generates the complete source code of a function declaration from a function's compiled form, fun
.
If successful, JS_DecompileFunction
returns a string containing the text of the function. Otherwise, it returns NULL
.
If you decompile a function that does not make a native C call, then the text created by JS_DecompileFunction
is a complete function declaration suitable for re-parsing. If you decompile a function that makes a native C call, the body of the function contains the text "native code'"
and cannot be re-parsed.
