Left() function location in CVI library

[Mark_K]

Trying to use  function >> Left(string, NumberofCharacters) that is available in TestStand in a CVI file. Cannot find which CVI library this is located in.  Above functions returns substring of argument string of length NumberofCharaters.

You can use strncpy (tgtString, srcString, NumberOfCharacters);

Please read carefully the online help for the function to understand its behaviour in the various cases: it is normally enough to add

tgtString[NumberOfCharacters] = 0; to ensure that the string is null-terminated, but you must be aware of strncoy behaviour with different lenght strings.

I have never come accross the left function in CVI. However, I believe the function StringCopyMax found in Programmers Toolbox>>String Handeling does the same function that you are looking for.
