The {{strncpy_s()}} function copies up to {{n}} characters from the source array to a destination array \[[TR 24731|AA. C References#ISO/IEC TR 24731-1-2007]\]. If no null character was copied from the source array, then the {{n{}}}th position in the destination array is set to a null character, guaranteeing that the resulting string is null-terminated. |
This compliant solution also guarantees that the string is null terminated.
