感觉你说的这个问题存在,自己可以在replace里判断模块。

如果我只想hook调用libc.so的open函数，假如一个so也实现了一个open函数会不会被误hook掉？
如果存在这种情况的话，程序本身运行就有问题了。C/C++ 函数名称冲突在链接的时候会有问题，你可以自己写个demo验证下，或者研究下动态链接器的原理。

之前说错了，xhook_register 可以通过正则表达式，指定模块名。

写demo验证了一下，的确会被误hook，mylibc.so中写了一个read函数，test.so调用mylibc.so的read函数，在APP中hook read函数，mylibc.so和libc.so中的read函数都被hook到了

我要hook所有调用了libc.so中指定函数的so，不能指定名称

不知道为什么hook mono_image_open_from_data_with_name，old_func总是NULL,而且程序会崩溃，不知道是不是跟参数有关，可是之前用adbi inline hook参数就是这样写的没有问题的
