dlinfo on android?

[Divij Kumar]

I have existing C code that uses dlinfo to get the details about the current running process. I use dlopen(NULL) to get a handle to the current process, and do a dlinfo on it.

 

However dlinfo isn’t available on Android (see /bionic/libc/includes/dlfcn.h) or do nm on libdl.so

Is there plan to support it. Is there an alternative?

 

Thanks,

There is no plan right now. Please file a bug on b.android.com about this if you need it.

Thanks in advance

Correct me if I am wrong, but this is not Linux functionality, is it?
AFAIK it's only on Solaris.

This works fine on both Linux and Solaris.

Yes, dlopen/dlclose/dlerror/dlsym are, but dlinfo?

[David Turner]

dlinfo is not posix but implemented by glibc's dynamic linker

You may try the following:
nm -D libdl.so

relevant o/p
000013b0 T dladdr
00001400 T dladdr1
00000ca0 T dlclose
00001170 T dlerror
00001490 T dlinfo
00001760 T dlmopen
00000ae0 T dlopen
000018d0 T dlopen
00000cf0 T dlsym
00000dd0 W dlvsym

Dlinfo is supported on most linux distros.
