The arguments and return value of wcscpy_s are wide-character strings those of _mbscpy_s are multibyte-character strings. These three functions behave identically otherwise.

1/11/2012 · In my project, I am using the wcscpy_s function. I went to the msdn website and they say that the second argument is the size of the destination buffer and when I build the project, crash. When I equal the second argument to the lenght of the source string, the programa runs without any error. Here is the function where occurs the error.
2/14/2013 · From the MSDN documentation of wcscpy_s: Upon successful execution, the destination string will always be null terminated. From the specification of wcsncpy (C11 7.29.4.2.2/1-3): #include h > wchar_t * wcsncpy(wchar_t * restrict s1, const wchar_t * restrict s2, size_t n), 10/23/2012 · wcscpy_s(_text, len + 1, text) The second parameter is the buffer length, not the string length. When I run your code, with just len, I get an assertion: Buffer is too small.
