 These functions try to append the first *D* characters of *strSource* to the end of *strDest*, where *D* is the lesser of *count* and the length of *strSource*. If appending those *D* characters will fit within *strDest* (whose size is given as *numberOfElements*) and still leave room for a null terminator, then those characters are appended, starting at the original terminating null of *strDest*, and a new terminating null is appended; otherwise, *strDest*[0] is set to the null character and the invalid parameter handler is invoked, as described in [Parameter Validation](../../c-runtime-library/parameter-validation.md).
 
-There is an exception to the above paragraph. If *count* is [_TRUNCATE](../../c-runtime-library/truncate.md) then as much of *strSource* as will fit is appended to *strDest* while still leaving room to append a terminating null.

 In all cases, the resulting string is terminated with a null character. If copying takes place between strings that overlap, the behavior is undefined.

 **wcsncat_s** and **_mbsncat_s** are wide-character and multibyte-character versions of **strncat_s**. The string arguments and return value of **wcsncat_s** are wide-character strings; those of **_mbsncat_s** are multibyte-character strings. These three functions behave identically otherwise.
 
-The output value is affected by the setting of the **LC_CTYPE** category setting of the locale; see [setlocale](setlocale-wsetlocale.md) for more information. The versions of these functions without the **_l** suffix use the current locale for this locale-dependent behavior; the versions with the **_l** suffix are identical except that they use the locale parameter passed in instead.

 In C++, using these functions is simplified by template overloads; the overloads can infer buffer length automatically (eliminating the need to specify a size argument) and they can automatically replace older, non-secure functions with their newer, secure counterparts. For more information, see [Secure Template Overloads](../../c-runtime-library/secure-template-overloads.md).
