strcmpi: does not return right result

[dkumar3]

It seems that I am not able to use strcmpi function properly.

  		bool res = strcmpi(FilterType, "TwoD");
		std::cout<< "response is " << res << "\n";

		bool res2 = (FilterType == "TwoD");
		std::cout<< "response2 is " << res2 << "\n";

I would expect the value of "res" and "res2" to be identical. But, this is not the case.

response is 0
response2 is 1

Some help would be appreciated.

strcmpi (and all strcmp family) returns 0 when strings are equal.

@MiiNiPaa, thanks. I was expecting it to return 1; hence, I was confused.

it does a bit more than that,

<0 for strings alphabetically less than
>0 for strings alphabetically greater than
==0 for matching strings.

strcmp compares content
== compares memory address

They are quite different things.
