此外问个问题,使用 xHook 之后,如何能够调用原本的函数返回呢?
如 hook malloc,myMalloc 仅记录内存分配信息,但是还是要调用系统真正的 malloc 方法返回。
from xhook.
我觉得可以通过函数指针直接调原来的malloc,不用担心死循环问题。

@AlphaHans 编译警告的问题我有空改一下,暂时请先使用readme中的方法用 NDK r16b 编译吧。
可以用 xhook_register
函数的最后一次参数,保留原 malloc 函数的地址,myMalloc 中使用这个函数地址来调用原 malloc。
from xhook.
@caikelun 有个问题请教,一定要用r16b么,hook修改的是data,感觉不是一定需要flush cache吧,会不会有其他后果。主要是我的ndk太古老不想换。
from xhook.
@fr0zenrain r16b是最后一个官方支持 armeabi 的版本,ndk版本太低的话bug比较多,建议升级哦。需要 flush cache,你可以把 flush 的逻辑临时去掉对比试一下。
