Empty String Overkill

[Blake Miller]

Is it just me, or does this seem like overkill to detect an empty string... if( strcmp( szPossiblyEmptyString, "" ) == 0 ) :doh: No shirt, no shoes, no brains, no service.

Yes, I usually do if (!(*szPossiblyEmptyString) ) But this maybe not very readable. Igor Green http://www.grigsoft.com/ - files and folders comparison tools

if (szPossiblyEmptyString [0] == 0) That works fine for testing for an empty string. If you also want to test for a NULL pointer if (pszString == NULL || pszString [0] == 0) Tim Smith I'm going to patent thought. I have yet to see any prior art.

That's a good habit, in case one has to work with BSTR strings.

Definitely superfluous. ;)
