[C-safe-secure-studygroup] null check

[Robert Seacord]

Is a null pointer guaranteed (by the C and/or C++ specification) to
evaluate to false?  For example, does the following C++ statement



                Std::string tmp(tmpPtrVal ? tmpPtrVal : “”);



Need to be rewritten as:



                Std::string tmp((tmpPtrVal != NULL) ? tmpPtrVal : “”);

Thanks,
