JSValue func = ... // some function CallData callData; if (func.isFunction()) { JSObject* functionObject = func.getObject(); if (JSC::getCallData(functionObject->globalObject(), functionObject, callData)) { // Use the callData object to retrieve information about the function call } }
JSFunction* func = ... // some function CallData callData; if (JSC::getCallData(func->globalObject(), func, callData)) { // Use the callData object to retrieve information about the function call }This example is similar to the previous one but uses a JSFunction object instead of a JSValue object. Overall, the JavaScriptCore library provides C++ APIs for interacting with JavaScript objects and data structures from C++ code. The getCallData method is a part of this library and can be used to retrieve information about function calls.
