Describe the Bug

` int my_log_print(int prio, const char tag, const char fmt, ...) { return 0; }

int disableLogcat() { bytehook_init(BYTEHOOK_MODE_AUTOMATIC, false); bytehook_hook_all(nullptr, "__android_log_print", (void *) (my_log_print), nullptr, nullptr); } ` 想拦截logcat的输出，但是hook没效果，logcat还是会打印

使用源码依赖，编译到自己so的方式

解决了，问题原因是在new_func函数里没有调用BYTEHOOK_STACK_SCOPE
