Replacements for Depracated NSIsSymbolNameDefined(), NSLookupAndBindSymbol()

I've been waiting for Apple to update its 'MoreUNIX.c' Sample Code to 
replace the depracated functions NSIsSymbolNameDefined() and 
NSLookupAndBindSymbol() and stop getting compiler warnings.  But it 
looks like maybe it's never going to happen, since MoreAuthSample has 
been replaced by BetterAuthSample (which requires 10.4.6 or later).

Does anyone know what these functions do and/or how to replace them 
with non-depracated functions?  They're declared in dyld.h in the 
10.4u SDK, but no documentation shows when searching API in Xcode.

Thanks,
