visual c++ - C++ - check if safe functions are needed -


When I am using Visual Studio (MSVC), and using the strcat function I'm sorry, then error me

error C4996: 'strcat': This function or variable can be unsafe. Consider using strcat_s instead. To disable exclusion, see _CRT_SECURE_NO_WARNINGS Use Online Help for details.

If I wanted to create a project that was for compilers such as GCC , then there is a way to find out whether it is safe Functions are required, for example MSVC macros?

You can use conditional compilation for cross-platam code such as:

< Pre> #ifdef win strcat_s (... #else strcat (... #endif

MSWC compiler recognizes such calls of such functions as acceptance reject Done and generate a warning at level 3. Therefore, just compile this level with (or more) and see the warnings.

Unmanaged & lt; Cfarray & gt; also means? I looked, but I do not need to change the array in a fast array (though it would be good). I need to be able to get value from the array. I also tried CFArray method to pass in a function: func doSomeStuffOnArray (myArray: NSArray) {} Although I get the same error when using: doSomeStuffOnArray (cfArr); // unmanaged & lt; CFArray & gt; I am using CFArray because I want to sto...
