描述
StringCchPrintf and--since C99--printf support a specifier that indicates that a string is counted:
auto size = /* ... */;
auto data = /* ... */;
printf("%.*s", size, data);
The .* suggests that printf should consume one register-width argument to determine how many characters the string that follows contains instead of waiting for a null terminator.
