Use the Microsoft Visual C++ tool Dumpbin.exe to generate a list of all symbols contained in the LIB files supplied on the SDK. You can then simply search that file for a given export. Bring up a Command Prompt and then with ER1 to ER5 SDKs do the following:
cd \epoc32\release\wins\deb
dumpbin /linkermember *.lib > Exports.txtand with any V6 SDKs or newer do this:
cd \epoc32\release\wins\udeb
dumpbin /linkermember *.lib > Exports.txt
Note: You cannot guarantee that exports will be the same across all variants, e.g. the MARM REL exports may differ from the WINS DEB ones.
