One liner:
WSDB::E:\snap\> dumpbin /exports db2app64.dll | grep DiagWhat 510 212 00BD1152 pdDiagWhatIsRc = pdDiagWhatIsRc
This isn’t an nm equivalent, instead is more like the AIX command to dump just the exported symbols from a shared object (dump -TvHX32_64), but enough to tell me that I shouldn’t have a link error this iteration of my build.
I found it curious that ‘dumpbin /symbols’ didn’t produce any output for this dll, as is does for a .obj file, and don’t really know what the reason for that is.
