objdump or nm exported symbols (was: Linker exposing private symbols)

[Jeffrey Walton]

...
$ g++ -o sha256_wrapper.so -g2 -O3 -shared -fPIC -ffunction-sections
-fdata-sections -fvisibility=hidden -fvisibility-inlines-hidden
sha256_wrapper.o ./libcryptopp.a -Wl,--gc-sections
$ nm -gCD sha256_wrapper.so | grep ' T ' | wc -l

Alan, Since I have you on the line...

Is there a more succinct way to objdump or nm only exported symbols,
without warts like:

nm -gCD sha256_wrapper.so | grep ' T '

No. :-(

Probably the closest that you will get is:

nm --defined-only --extern-only <foo>

But this will include exported data symbols as well as function symbols.

Cheers

Ack, thanks.
