On my Windows/Visual C environment there's a wide number of alternatives for doing the same basic string manipulation tasks.
For example, for doing a string copy I could use:
First of all, let's review pros and cons of each function set:
strcpy are the one and only choice if you are developing portable C code. Even in a Windows-only project, may it be a wise thing to have a separation of portable vs. OS-dependent code.
These functions have often assembly level optimization and are therefore very fast.
There are some drawbacks:
lstrcpy are exported by kernel32 and should be used only when trying to avoid any dependency to the CRT. You might want to do that for two reasons:
Moreover, the kernel32 function could be more optimized that the CRT version: when your executable will run on Windows 9 optimized for a Core i13, kernel32 could use an assembly-optimized version.
Here are valid the same considerations made for the kernel32 functions, with the added value of some more complex functions. However I doubt that they are actively maintained and I would just skip them.
StringCbCopy functions are usually my personal choice: they are very well designed, powerful, and surprisingly fast (I also remember a whitepaper that compared performance of these functions to the CRT equivalents).
These functions have the undoubted benefit of being very similar to ANSI C equivalents, so porting legacy code is a piece of cake. I especially like the template-based version (of course, available only when compiling as C++). I really hope that they will be eventually standardized. Unfortunately they have a number of drawbacks:
While my personal favorite for Windows development is the StrSafe library, my advice is to use the ANSI C functions whenever is possible, as portable-code is always a good thing.
In the real life, I developed a personalized portable library, with prototypes similar to the Security-Enhanced CRT functions (included the powerful template based technique), that relies on the StrSafe library on Windows and on the ANSI C functions on other platforms.
