ACE_WCHAR_T * ACE_OS::strsncpy ACE_WCHAR_T *  dst,
const ACE_WCHAR_T *  src,
size_t  maxlen
 

This is a "safe" c string copy function (wchar_t version).

Unlike strncpy() this function will always add a terminating '' char if maxlen > 0. So the user doesn't has to provide an extra '' if the user wants a '' terminated dst. The function doesn't check for a 0 dst, because this will give problems anyway. When src is 0 an empty string is made. We do not "touch" * dst if maxlen is 0. Returns dst. Care should be taken when replacing strncpy() calls, because in some cases a strncpy() user is using the "not '\0' terminating" feature from strncpy(). This happens most when the call to strncpy() was optimized by using a maxlen which is 1 smaller than the size because there's always written a '' inside this last position. Very seldom it's possible that the '' padding feature from strncpy() is needed.
