[Valgrind-users] About how to get the guest code memory

[shuai xi <aha...@gm...>]

Hi@all,

I add some hooks in the vgpreload*.so and get some information from it. The
vgpreload*.so is a dynamically library  loaded in the guest code.

I want to get this information to do some analysis. But i don't know how to
get this information from guest code memory to valgrind memory space.

I attempt to use a global variable to store this information, but valgrind
show me a error that it can not find this global variable's symbol. Because
this global variable is in guest code memory space.

I attempt to write this information in file, because i hook the function
malloc.

Is there some solution like 'share memory' to deal this problem？

Very Thanks
