/***
|
|
*wchar_t *wcsncat(front, back, count) - append count chars of back onto front
|
|
*
|
|
*Purpose:
|
|
* Appends at most count characters of the string back onto the
|
|
* end of front, and ALWAYS terminates with a null character.
|
|
* If count is greater than the length of back, the length of back
|
|
* is used instead. (Unlike wcsncpy, this routine does not pad out
|
|
* to count characters).
|
|
*
|
|
*Entry:
|
|
* wchar_t *front - string to append onto
|
|
* wchar_t *back - string to append
|
|
* size_t count - count of max characters to append
|
|
*
|
|
*Exit:
|
|
* returns a pointer to string appended onto (front).

*Uses:
